I Had A Flying Dream Or Was It A Obe?

One day I was in my room looking out the window just yearning to climb my window push the ceiling up and take off flying. I had plenty of dreams where I. Was flying but this one felt strange. Ok it was about 5 or 6 in the morning when I had this Experience. It started out with me and my mother arguing and I was talking bad to her and once I got outside in the front yard I took off running and flew straight up in the sky now pause a minute. I took off first of all because I thought my mom was after me now as soon as I took off flying I saw the sun the cloudy sky and it looked scary amazing. Soon after I flew up in the speed of light I was outer space now this what scared me when I realized I was out of space this is what I saw; darkness surrounding me and I saw the earth underneath me and as soon as I saw that I panicked so hard that I felt my eyes bucked open and they open in my awaken life and when they open I still saw a little of the earth in my eyes as if my eyes had white dots in them and I felt myself falling back into the earth. Why do I have these dreams where I fly into outer-space and stop I wish to keep going beyond it hopefully to another galaxy. I truly think its impossible to travel to galaxies and dimensions in the physical world but only during sleep or naps that you visit these unseen places. I had experiences where I dozed off and fell into a low dimension state of mind and know detail by detail of what I saw and why I think it was a lower dimension and the I saw my dead cousin on a bench, and she got in my face, spoke to me and I jumped out the state of mind.
