A dream in a dream

I'm not sure of the structure of the dream I had last night. It was either two separate dreams, or it was a dream in a dream. I don't remember much about the first part, except that the first dream was a nightmare full of monsters, and I was honestly terrified of it. I woke up crying, if that means anything. For the record, I usually enjoy nightmares. They are a thrill ride, but not this time.

The second part was also a lot of fun, but I can't remember much about it either. All I remember was that it was not a nightmare, and it was really cool...
