How Phasmophobia Ghost Behaviors Actually Work in Practice
The ghost in Phasmophobia isn't a random encounter generator. It follows a set of behavioral rules that change depending on difficulty, ghost type, and what evidence you collect. I learned this after six hours of watching the same room go cold, triggering EMF spikes, and never finding the door locked when I expected it to be. Most players start by reading a Phasmophobia Ghost Behavior Cheat Sheet and treating each behavior as a one-to-one mapping to a ghost type. That's wrong. Behaviors are probabilistic. A Revenant can still raise EMF to level 5. A Mimic can still drop temperature. The cheat sheet tells you what's possible, not what's guaranteed.
Reading the Phasmophobia Ghost Behavior Cheat Sheet Without Misleading Yourself
The official evidence system rests on three pillars: EMF readings, temperature drops, and spirit box responses. Every ghost type leaves a unique combination of two or three of these. The DOTS projector and ghost writing book add a fourth and fifth option on higher difficulties. When you find yourself in a room with no lights, your hands shaking around a thermometer, you need to know which behaviors to prioritize and which to ignore. I ran into a specific problem at the Maple Lodge Cabins map during a hard session. The ghost was triggering freezing temperatures below zero Celsius in the bedroom, and I had EMF level 5 appearing on my reader. That combination pointed straight to a Spirit according to every chart I'd seen. But the ghost was also locking doors and moving objects rapidly when we entered the room. No Spirit locks doors. A Yamatai can lock doors and drop temperature, but it doesn't produce EMF 5. I spent twenty minutes arguing with my teammate about whether we were chasing a glitch or misreading the evidence. We weren't. It was a Phantom, and on hard difficulty, the temperature drop and EMF 5 were both active behaviors, but the door lock wasn't from the same ghost cycle. The workaround: I stopped trying to pin one ghost type and instead used the thermometer as the primary anchor. Temperature events are almost always reliable regardless of difficulty scaling. EMF and spirit box responses fluctuate more on harder settings. Once I treated the cold as the ground truth, the rest of the evidence fell into place.
Core Behaviors and What They Actually Tell You
Let's talk about the behaviors themselves before we get into ghost type assignments. The first category is environmental. Temperature drops happen when the ghost is active, usually when you're nearby or making noise. The average drop is between five and fifteen degrees Celsius, but it can go lower if the ghost is a Oni or Yurei. The second category is electromagnetic. EMF readings appear on your device when the ghost is interacting with electronics or just generally being present. Level 5 is the rarest and strongest signal. The third is auditory. Spirit box responses, haunting sounds, and EVP recordings give you clues about location and intent. I've found that most beginners over-index on spirit box results. The ghost can give false positives on normal difficulty, and on hard mode, the response rate increases but so does the chance of ambient interference from radios left on in the same room. A single spirit box word like "death" or "leave" shouldn't override the physical evidence. Use it to triangulate, not to decide.

Ghost Types and Their Behavioral Signatures
There are over twenty ghost types in Phasmophobia, and each has a distinct profile. A Banshee only targets one player at a time and becomes invisible during hunts. A Mare prefers hiding in dark rooms and attacks players who are alone. A Yurei drains sanity fast but is weak to light. The list goes on. What matters for survival isn't memorizing every type but recognizing patterns in the behaviors you observe in real time. Here's a counter-intuitive insight: the ghost type with the most extreme behavior is often the easiest to survive against. The Wraith teleports and leaves no footprints, which makes it unpredictable, but it also avoids close contact during hunts. The Hantu freezes players near it, which sounds dangerous, but the freeze slows movement dramatically and gives you time to react if you're not cornered. The more terrifying ghosts tend to have simpler AI trees. The complicated ones, like the Myling or the Deogen, have nuanced trigger conditions that require you to pay attention to multiple variables at once. The Myling produces sound constantly, even when it's not hunting. If you hear faint footsteps or door creaks on loop, check your spirit box first before assuming it's atmospheric audio. The Deogen changes speed based on how much sanity the nearest player has. High sanity means slow. Low sanity means fast. If you're running from a Deogen, don't hide in a corner and pray. Move toward areas where you can maintain medium sanity, ideally above forty percent, to slow it down.
When Behaviors Fail and What to Do Instead
No cheat sheet covers every edge case. There are scenarios where ghost behavior breaks down completely. During a full moon phase in the game, some ghosts become more aggressive and trigger behaviors more frequently. On custom difficulty settings, the sanity drain rate can be modified so much that you never reach the threshold required to trigger a hunt, but the ghost still performs interactions like writing on the ghost board or freezing rooms. In those cases, you're collecting evidence without any hunt threat, which is either a blessing or a waste of time depending on your goal. Another failure mode I've encountered is the Ghost Writing book. The book records ghost interactions with written messages, but it only works if you place it in a room the ghost can access. If the ghost is locked in another wing of the house, the book stays blank. I learned this the hard way during a night at the Asylum. We spent the entire session writing down notes that never appeared, thinking the ghost was inactive. It wasn't. It was just in the basement, and we kept putting the book upstairs. Move the book to the coldest room first, then check it periodically. If you're playing solo and want an alternative to the cheat sheet approach, use the thermometer and EMF reader as your only tools. Skip the spirit box and DOTS projector entirely. This reduces noise and makes the signal clearer. You'll miss some ghost types that only reveal themselves through paranormal audio, but you'll catch the ones that matter for survival.
Practical Tips for Real Sessions
Bring a portable heater if the temperature is dropping too fast. A heater can keep your sanity above fifty percent for twenty minutes longer than you'd expect. Carry spare batteries for your equipment. Dead batteries mean dead evidence. Keep a notebook or use the in-game log to track each behavior event. Write down the time, location, and type of interaction. After the session, review the log to see if a pattern emerges. Most players skip this step and repeat the same mistakes across multiple nights. Don't trust a single piece of evidence to identify a ghost. Even on easy difficulty, the ghost can mislead you by producing fake EMF spikes or false spirit box words. Use the evidence as a cluster. Two or more consistent signals pointing to the same type give you confidence. One signal alone is just a guess. The final thing to understand is that Phasmophobia is designed to be unsettling precisely because the ghost adapts to your behavior. If you keep entering the same room, it learns to expect you there. If you always hide in closets during hunts, it starts blocking those exits. Pay attention to your own routines and break them occasionally. Randomize your paths. Change your lighting strategy. Make the ghost work for its moments.
That's how you survive long enough to collect the evidence you need and figure out what kind of entity you're dealing with.
