Telepathic powers? Check!
People after me? Check! (Though I never thought it was CIA or government or anything, I'd be like, "people are after me! But, not the government that's what crazy peoople think!" As proof I wasn't crazy)
Doctors screwing with my meds? Check! I was convinced that my doctor was trying to make me insane so he could feed me to a cannibal in a psychward.
Insivible people and alternate realities? Check!
Hearing voices? Check!
Seeing things? Check!
People I am close to being replaced by monsters or demons? Check!

This happens when depressed too.

When depressed I might believe I've already committed suicide and that I'm dead and in hell. Even failed an attempt and used that as proof I was dead and my existence is immortal. Everything would be out to get me. Objects would "speak" to me to inflict pain and suffering.

Odd part is, a lot of the time when I'm like that I *know* it isn't right but at the same time I know these strange things are real which leads to a lot of confusion and secrecy which leads to more paranoia.

I too haven't shared much of it with doctors. A little but, I get really sensitive about it and always feel like they don't believe me anyway, because I know I shouldn't believe me!
