I had a good laugh reading this.
Once I had a dream in which a tau-cannon arrived inside my mailbox out of nowhere. I qucikly unpacked it and took it outside to test it out. I started boosting around everywhere with the wind whistling through my ears, one time I even charged it too much and got so high that I thought I was going to die. Right before I hit the ground I managed to edgebug from a stump and I was so relieved to make it to the ground alive.
I wish I had more dreams related to speedrunning. Most of them are about plain bunnyhopping without any interesting twists.
