I have never heard of lucid dreaming until just now. I told my friend about how I controlled a dream.

When I got into a deep sleep, I had a dream that I was at a theme park. I saw nothing around me but trees and a single ride.

3 of my friends that I havent seen for 3 years were with me (but we just talked on the phone the day before). We got on a very tall ride that rotates in random directions. I noticed that there were NO seatbelts. People were just holding on to a bar as their body flung in directions. I was worried about falling, but then noticed that I was practically stuck onto the bar. It seemed to fake to be true and I somehow ended the ride, turned around, and there was a BRAND NEW ROLLERCOASTER. (That wasnt there before.)

I got on the roller coaster and controlled it to go backwards. It seemed almost real!

Would this be classified as lucid dreaming? If so, I really want to learn how to do this. I dont ever remember my dreams unless I sleep well. Are there any tips like eating/drinking before sleeping or what sleep position is optimal? I really want to have that experience again!
