Extreme Deja-vu Feelings

I have been experiencing these strange feelings now for a good 2 years. I had them very sparingly and they were much more mild than they have been during the last year or so. I have a feeling of extreme deja-vu. It is like dreaming while awake but after it happens I cannot remember the dreams. I feel panicky and I used to think it was panic attacks but I do not think it is that anymore. I noticed another girl on this site (Buttahflyy130) that experiences very close to the same things that I do. Like her, I never know when it is going to happen but when it starts it usually goes on for 3 or 4 days in a row. It happens during sleep now which it never used to. Now these strange feelings happen at random times throughout my day and while sleeping. They make me sick to my stomach and I lose my appetite for days. Most recently I lost about 5 pounds in less than a week from the stress of these deja-vu feelings. It is getting stronger and the last time I actually felt like something was with me trying to tell me something. It is so hard to explain to anyone but it is very very real. I never know when it will happen and I too have tried to tie it to my monthly cycle or hormonal changes, maybe what I had eaten, etc. Nothing makes sense. It is most horrible when I am driving and it has happened many times when I am driving. It makes me scared, nauseous and depressed. It was happening pretty regularly for awhile, once every month for 3 to 4 days in a row. Mid July was the last time I had it happen except for a few mild episodes during sleep and a few during the day that did not really effect me until these last episodes occurring in the latter part of October. After this last 3 to 4 day episode I was left very absent minded and forgetful for at least a week, probably because it happened more times during the day and night than ever before plus more severe feelings. I am just now feeling back to normal only to wonder when it will happen once again for 3, 4, 5 days in a row and then disappear and wonder how much stronger these feelings are going to get. And at times it has felt like an out of body experience for me as well. I just wish it would go away and never come back... I would love to be able to talk with Buttahflyy130. I was so relieved to at least find someone else out there that is experiencing close to what I am.
