Weird nightmare

I didn't know a nightmare could freak me out so much like this. I woke up really early in the morning and I couldn't go back to sleep, then I started reading a little bit the Bible and prayed until I fell asleep. The only thing I remember, is that I was climbing a "pole" and trying to get to the top. While climbing, I was thinking that after the level 59, only God could get there. I was almost at this specific level, when an eye suddenly appeared and started staring at me. Suddenly, I was laying down on the bed and almost "levitating" but it wasn't in a good way, and it felt like it was a evil spirit trying to do something to me. I woke up, and I kinda screamed and was trying to breath at the same time. I fell asleep hugging the Bible. I was sweating and really scared. Just wanted to share, because I got really scared. Does this mean anything? Or it was just a nightmare?
