Bottle of Pop Anyone?

I am now recording my dreams in a dream journal which I keep at the side of the bed. Every now and then I have a completely mind blowing dream which I could not possibly create out of my day to day imagination.
The other night I was flying over and through mountains and then ended up in the most bizarre situation. I was apparently an air bubble in space. I had the most overwhelming feeling of a massive, black void and I was rising and pushing against the blackness. I could feel that there was an end or a 'ceiling' and I enjoyed every moment of the struggle towards the surface.
