Hello! A few days ago I thought of a scary (or rather thriller) movie, but I can't remember its name. It was a group of students who went on vacation, if I'm not mistaken. There was a teacher with them. They had gone somewhere by the sea to one of the students' house. The student (with the house) also has an older brother who is "crazy" ... So everything goes well, while some of the students start taking a drink / cocktail (made according to an old tradition, May) and causing hallucinations (something like their worst nightmares or fears), most of which (not to mention all) committed suicide in some way ... They had put the drink in the teacher's glass .. he "saw" how he attended a sacrifice ritual (he was the victim) and a girl motioned for him to approach her. He followed her, but in fact he was going to the sea, where he drowned ... And the "crazy" brother has been taking this drink for years and sees in his brother's girlfriend the girl he needs for this sacrifice ... I only remember this + that this "crazy" lived next to some abandoned greenhouse ... And of all the others only about 3-4 survivors ... If anyone thinks of the movie, or similar, write a comment! :)
