No, but I feel like I might as well recount my only remembered nightmare here. Why not, right?
So, I'm walking into my grandparents' bathroom, and as I come in and close the door, I look back at the shower and a black... erm... well, imagine a sort of stereotypical alien, except it's black, and human sized, and its head is way bigger than the normal alien-head. That is standing behind the curtain (transparent curtain), and it reaches with its left hand over to the right side of the shower, and pulls the curtain out, revealing itself fully, and it just stares at me. It glares directly at me with an expression which is the normal expression for the stereotypical alien-head, but when put into a human head, it looks furious. So it looked furious, and it glared at me intensely, and it seemed to be approaching me, but I don't think it was because its feet or legs weren't moving, and it couldn't be floating because there was a tub blocking its way, but psychologically, it appeared to be slowly coming down on me. My grandpa woke me up, and said I was gasping for air and convulsing on my bed.
That's the version with logic applied so you can understand what was going on. You'll have to translate into dream material yourself. I'm certain you're able to.
It was very, very frightening to me.
