I've done a short journey before, from the Earth to the Sun.

When I became lucid, I remembered I wanted to go directly to the Sun and the next thing I know I was just outside the Earth's orbit looking at it from a distance. I started to fly towards it and the radiation would powerfully zap my body and i would loose conscousness as I got closer. So I decided to teleport DIRECTLY INFRONT of the Sun... big mistake! It was the the most terrifying awesome thing I've ever experienced. I was suddenly faced with the absolute insane hugeness and powerfulness of it, the enormous roaring electrical noise and it's majestic fierce power. It tore apart my very being in an instant and I woke up. I must have been there for a fraction of a second.
