A while back I was sleeping in my girlfriend's bed while she had classes. I had none, so naturally I decided to sleep all day. She woke me up around noon by accident and I dozed back off and started having a semi-concious dream. In the dream, I was driving my car with some friends in it and they were talking. It was incoherent, but the conversation got louder and louder until it seemed like I was actually there - really there inside the dream. The same instant I realised that, I was thrust upward and heaved into a kind of tunnel. It seemed as though I was flying and completely in control of everything. Whether voluntarily or involuntarily, it stopped suddenly when I reached some strange symbol in the tunnel. I woke up with my body tingling everywhere - and only a few minutes after I had dozed off, if that. So I've been curious for a while now if this was actually an out-of-body experience or just a mild stroke...
