So I have never really experienced a truly lucid experience where I was both aware of the fact that I was dreaming and able to mold my dream from being aware.

However yesterday I read about lucid dreaming from Reader's Digests and it really got me thinking. Going to sleep that night it took me longer to fall asleep and when I did something strange happened.

A disturbing image of a mask started gravitating towards me and after a while vibrated and kept flying towards me. The sound it made while doing that felt surreal and was very loud. I tried waking up and opening my eyes but they would not, then with my arms and hands to the same results. It then got to the point where I felt I was suffocating and now I was genuinely scared. Finally I managed to concentrate and move my feet and eventually my leg which led me to awake.

This experience felt like it lasted 10-20 seconds but in actuality I don't know how long it was.
