I've had this strange thing that happens to me for a few years now, but lately it's gotten much more frequent and the symptoms much more pronounced. It can happen any time. I could just be sitting, at work, driving, at school, any time really, and all of the sudden I get this strange feeling that totally overtakes me. I get these thoughts in my head, almost as if I'm trying to remember something but I can never quite put my finger on it. In addition that, when it happens I get a very uneasy nervous feeling that lasts untill I snap out of it. It'll usually last just about ten seconds, and happens more so when I'm very tired. Unfortunetely whatever it is I'm trying to think of completely dissapears after it's over. I have no idea what this is and why it happens. If anyone thinks they know what it is, please tell me, and if you know what I can do about it. Thanks!!!!
