I am in the mood for writing tonight

Astral Projection
This happened when I was a teenager also (many moons ago). I had no idea what this was for another ten years after.
I laid down in the afternoon. I wasn't tired, just bored. Also I am the type of person who never, ever goes to sleep straight away, my mind ticks away for a long time.
After just a few minutes after lying down I was suddenly in a huge glasshouse (about as big as half a football field). I could see the bright blue sky outside. I was lying on my back, on what seemed like lush, vibrant green, grass, which I knew was fake, (actual fake grass) but felt nice, like real grass, and the ground I was lying on was rolling, perfectly like big rolling waves. It was the most enjoyable, blissful, comforting feeling. I decided to conjure someone up in my imagination to join me and that ruined it....I was back on my bed, wide awake. I ran out, really excited about my experience, to tell my flatmate/best friend and she looked at me like I was making it up, which hurt my feelings.
