Thread: Book Reading Wild ?!?!

Hey you all
Last Night I experienced the strangest Wild EVER! I was very tired because I only got about 2 hours of sleep in the last 2 days and when I wanted to sleep I realized that I had to read 50 pages of a book for school.
So I got my book and started reading...
After about 10 minutes the strange thing happened. I got really sleepy while reading the book but I forced myself to go on. I slowly noticed how my mind was making up a dream scene (like when you deild the scene slowly appears) while I was reading. At first I didn't focus on it but after a while it got strangely vivid. I was playing LoL (yeah I know, I know...addict hehe) inside my head and my mind was making up a complete match with all the players doing something different without me having influence on anything. At this point I was still reading the book and my eyes were open. After it went on I realized that I was in some kind of trance. I was still looking at the book but I was completely deepened in the scene. At this point I tried to actually influence on the scene and tried to somehow "enter" it. Immediately everything went crazy and it felt like I was getting sucked inside a black tunnel in my head. When it was over I realized that I was dreaming and had a awesome ld!
When I woke up again my eyes were still open but they were pretty dry and it hurt

Now I wanna know how this is possible ?! I mean how can you actually enter a dream while having your eyes open? Is it because of my sleep deprivation? And if so, would it be actually helpful to deprive yourself of a little sleep just to wild?
