Seeing dead people

If it's that it's fine. Enjoy.

If you 'see' them in the sense most here have understood but still can tell the difference to real people you are seeing that is if at least in a small part of your knowledge you realise that this 'reality' is different from the daily reality (in a way like you can tell it was a dream although it did feel real), try to find people with similar experiences to talk. It is quite probably fairly harmless.

If you see them and they are completely real to you, as real as the computer keyboard in front of you, seek help (don't go to a psychologist, go to someone with a sound neurological background). They should send you to a brain scan I'd say. You BTW, in this case you are more dangerous for yourself than for others.
