Riddle 1

I am a tale in childrens’ minds.

I keep their secrets and share them inside.

I blur their thoughts into fantasies kept

Like a canvas of art or a submarine depth.

Though an illusion, it occurs every night;

I give them a fantasy, I give them a fright.

Nor good or bad, but always nigh’

It’s interesting to tell.

What am I?
