the difference between a dream and a nightmare

I am walking.

There is a sprinkler up-ahead.

I am made aware of this.

There are no thoughts.

I wake up.

There are thoughts :
“Man I hope that sprinkler doesn’t squirt me, maybe I’d better move out of the way.”
“man I better time myself to run through it just right so I don’t get wet.”
“Man I don’t want to get wet, I’d better not walk this way.”
Nightmare - you get wet.

“Oh, there’ s a sprinkler up ahead, I hope I don’t get wet.”
“Oh, I won’t.”
-Normal dream.

“Oh I can CONTROL wheter I get wet or not.”
-Lucid dream.
