I had this happen to me a on 2/9. I had not recalled very much of my dream from that previous night and didn't sleep well so I took a nap. I had lucid and non-lucid dreams but what is really odd and I hadn't really experienced before was this:

I am in the field but I do not have as much control as I did over my surroundings, I will call this more half lucid because I thought I was imagining it but couldn't put the imagining and dreaming together. Like it was a thought in my head but I didn't think it was yet a dream, really weird feeling lol.

But, I get up and get in a plane, I want to go far far away and see what else is there, I begin to take off as the field is fairly clear, as I approach the end of the field I get a little height, but not enough to take off. I bounce and land on the water but keep moving. I hit pieces of debris floating and see other planes trying to take off. My plane doesn't make it all the way and I crash.

As I crash I have a false awakening and go back to sleep again but what is weird is that in one field of vision I woke up or felt and saw like I did and I was in a different house; whereas, in the other field of vision I watched the plane wreck, in yet another field I experienced the BMX track, and finally one field was completely blank. I stand there as I am in a BMX dirt bike trail and for a minute I am rather confused by the whole situation. I tell myself to wake up and start over because now my mind was too broken up and I couldn't think straight with all of these dreams going on.

Part of me felt awake, part of me was in the BMX dream, part of me was in the airplane dream, and one more part of me just felt nothing. It was like having four dreams at once. Each was different and all were going at the same time. I could see and comprehend and interact in all of them.
I have never had this happen before it was similar to when lucid being in two places at once but these were separate dreams. They weren't completely perfect, each one was partially fragmented but it was really strange to me.

I just want to know if anyone else experiences this or has experienced it, and if so any way of sustaining it so that it is not so fragmented.
