nightmare

I'm standing in this big metal room that is very cold and looks pretty familiar, I start getting this de' ja vu feeling which causes me to become lucid. I have no body and I'm just a floating ball of awareness, and I start hovering around this room. All of a sudden one of the walls becomes magnetic and my awareness gets pulls towards the wall. The force is so strong I feel my awareness getting crushed, and I swear it's the weirdest feeling. I was thinking "It's okay, It's okay it's just a dream", but it felt to real. I then thought, HOLY **** AM I DIEING?!, i could feel my awareness getting crushed up against this wall even harder the more I panicked, I then woke up. This was my very 1st nightmare of a lucid dream.
