Nightmares

I watched a scary movie,
so I had scary dreams,
but I’m not sure what nightmares are.

Are they a mix of scary and happy?
Are they sad?
Maybe glad?
I do wonder what they are.

Maybe I’ll ask
my bro or sis,
but how should they know?
I wish I knew.

I asked my dad.
He said they are scary dreams.
I should have guessed
that I knew that all along.
