Suggestions for Future Horror Games

[Damascus Rose]

Basically monsters which act abnormally and you can't figure out any distinguishable patterns in their behaviour. A monster that seems to act differently all the time (randomized is an option), for an example a monster, such as a grunt entering the room where you are hiding. It walks up besides you, and seemingly doesn't see you. You then see it start walking away slowly and forgetting about you, when suddenly it turns around immediately and runs straight at you, ready to tear your face off.

Of course, it doesn't have to be all randomized behaviour, just behaviour that is very confusing to figure out.
