Is it normal that my friend is seeing aliens?
I know my friend's been taking quite a lot of different drugs and he's always been alright, but now he keeps telling me about his alien encounters and how he believes that a supernatural humanoid species will take over the world in 2012. He says that he keeps seeing these purple creatures talking to him in the forest and claims that all of his friends have seen them too even all of them deny this...
I don't think that this is normal and I'm probably going to try to talk him into seeing a psychiatrist soon...what do you think?
