For a few months now, I've had weird experiences. I'm going about my daily business when suddenly, its as if iv'e had a very, very vivid 'Memory' gets forced into my thoughts. Its not an hallucination, i can't see or hear anything. It's just that this memory is so strong. But the more i try and solidify it in my mind, it starts to fade until I'm left with nothing other than the knowledge that something strange has just happened. While its happening, i can still function normally.
Any help/advice would be great.
Thanks in advance.
