I had similar experiences
1st I was sleeping than the world just went upside down and my soul fell into the ceiling but my body stayed in bed and whatever I did I couldn't get back
2ndly (I keep seeing this alot) I'm walking in a muddy field towards 10 german machine guns and holding a Lee Enfield in my hand until it all goes dark.
And lastly this was my first dream I ever dreamed I was talking to this superme being (God?) and asked him if I could go back to earth and he just said yes and it all ends. And all those 3 dreams were so vivid as if I was living trough it in real life.
