I believe that hallucinations and psychic memory are real. I just have never known them to exist in the same person. If you know of a place and it exists, and you have never been there, I would say it was a psychic memory. My husband used to have them about being on a Navy ship while bombs were falling all around him. While watching a special on Pearl Harbor it all became very real for him. I believe he was there in a past life. In saying this, I also know that hallucinations can seem very, very real at times. Your choice. By the way, are you a beekeeper? I used to keep bees and found it very relaxing and a pleasure to do. They hated my husband tho and I swear would fly butt first for him lol.
I had something similar happen while psychotic where I felt like I was remembering things before they happened. I don't even know how to properly describe the experience except for that.
Hallucinations do seem real when they occur. I experienced them before recovery and they did take over my mind and seem real at the time but when I look back they weren't. Best thing to is speak to your psychiatrist about it. If something keeps you from being grounded in reality its generally not a good thing.
