I've had the deja vu feeling many, many times. A few years ago, DH and I were driving into work (he was driving, I was in the passenger seat) and I remember that I had this horrible headache. I remember looking at this semi-truck in front of us and experiencing that deja vu feeling where your stomach drops. Then I felt really tired so I laid my head back on the seat and closed my eyes. Next thing I remember is my DH yelling my name and asking if i'm ok. I guess I had a seizure. Never had one before! So after going to the ER and them finding nothing, they referred me to a neurologist. This guy was a kook! He didn't seem to understand the deja vu stuff I had felt before the seizure. And he kept pronouncing it as deja vwaa. Drove me NUTS. And then he was all about getting me onto some pretty heavy duty seizure medication...for one seizure...i'd never had them before and have not had one since. The doctors weren't convinced that I had even had a seizure to begin with. I put my foot down and told him that I would not be filling that prescription. If I had another seizure, I would be the first in line at the pharmacy.
So now, when I get the deja vu feeling, I get freaked out! Doesn't happen often, but it still happens every now and then! I'm happy to know that I'm not the only one who experiences these!! Anyone else I talk to about it has no idea what i'm talking about!
