What is the worst nightmare you've ever had?

I have a recurring nightmare where I'm stuck in a maze with a faceless man in a blue jumpsuit is chasing me with his arm reached out towards me. I always almost escape him then i come to a dead end and he walks up to me stammered try to catch his breath i guess but he doesn't have a face no nose nothing so i don't know but before he can get me every time i wake up...

If anyone could tell me what the hell it's about too that would be awesome. 😥
