Coinception

The most vivid of my dream occur in late mornings - not surprising, given that usually by now I'd be in waking life - and it was the only fragment I remember. This one happened roughly 10 - 11 am.

Oxygen is paramagnetic. That means at low temperatures, it is attracted to a magnet, and to magnetic fields. Oxygen is a liquid at low temperature, but here in front of me, I had a 0.5 x 0.4 x 1.2 inch sample of SOLID nitrogen.

Here I was, in my semester two chemistry class. Anyway, This solid sample looked rather like some coarse granite, though more greenish and with finer grains. It was submerged on some sort of floating circular spoon, within a water bottle. I reached in to touch it using my finger, and it burned. However when my nose went near it, not sure how given it was a bottle, it didn't burn, but only felt cold. We submerged it in the water slightly, and it started to fizz.

I knew that liquid nitrogen expanded explosively when converted to gas, but that is not what happened here. Soon, I took the spoon thing and submerged the entire nitrogen solid packet underwater, where it started to boil violently. We drained out the water, and then poured in some soda water, which turned the water greenish and made the boiling into some inverted vortex plume.

There was a guy in my class I don't get along with, and I hope he is not in my class. There was also a girl near the chalkboard, who asked me what I was doing. Thought I might get into trouble, because I had just destroyed a sample of expensive solid nitrogen.

Nevertheless, I wondered what would happen if salt water or just plain salt were poured onto the solid nitrogen sample.

That's when I woke up.
