I had a dream about a snake called The Vault. I was in my house, but my house was, for some reason, a lot bigger and richer than our normal house, and sort of like a palace, with massive indoor hanging gardens. I was in the gardens and there was a snake, whcih scared the shit out of me. It didn't attack me, so I avoided it. After a while it seemed to be following me around so I got scared as shit and attacked it and tried to kill it. IT WOULDN'T DIE. So now it was pissed as fuck at me and was chasing me around the place. I was trying to kill it but IT WOULDN'T DIE. My dog came to protect me, barking the shit out of the snake, but the snake wasn't scared. So we had a final stand in my bedroom - I got in my bed, and my dog sat on my arm and growled at the snake. I realized I needed to GTFO out of there because the snake was about to jump, but my stupid dog trying to protect me was sitting on me and I couldn't move. For some reason my mind produced a laptop at this moment and, with my hand that was free, I looked up wikipedia and saw that the snake was called "The Vault", and that it was indestructable and people usually moved to a different house when it was sited. All of this while I was scared shitless and being chased by an ultra fast snake - dream logic. So it was coming and I got so scared that I woke up.
This is actually really weird, because the thing that gave me "sleep paralysis" was a friendly creature trying to protect me but really holding me back. Usually the thing that sits on you and causes sleep paralysis is an evil presence, such as a demon that wants to rape you (my dog didn't rape me BTW).
Strangest nightmare I can ever remember.
