Is that the movie were a group of friends do shrooms, and while they are tripping someone is killing them off one by one? I'm pretty sure that's it, but I can't remember what anyone or thing looks like haha.
Oh wow... this is a very interesting and unique take on fear here - and quite brilliantly illustrated here as well. The monster's design, and its lurking presence, just it makes it that much more ominous and terrifying. Absolutely fantastic!
