I was being pulled by my arm across a room by some unseen force.
The 'thing' doing the pulling did not know I was aware of the situation.
I decided to grab ahold of the hand pulling me, and pull back.
The 'thing' changed into a scary face from some childhood horror movie.
I was not impressed, and became annoyed, then gripped its wrist, and pulled back, aggresively.
The 'thing' changed into a small, skinny figure like a Grey Alien. It was very scared of what I had done.
I saw its fear, so I smiled, and let go of its wrist.
Dream ended rather abruptly after that.
Very clear lucid dream, that one.
