Last night was my first time trying mirrors as portals. I tried with this small rectangular mirror, first it was my hand, then I decided to introduce my head and everything I saw was fog, I continued with the rest of my body but I got stuck , so I had to go back and continue exploring the dream environment. Fortunately I found a full body-sized mirror in the next room and I jumped into it, then started to fall in a dark space until I was ... for lack of a better word... spitted out in earth's stratosphere, incredible view btw, but kind of scary and imposing.
