I don’t have dreams (that I can remember) that often, but when I do they can be weird. Here is what I can remember of the dream I had two days ago. Some friend of mine (whom I only knew inside of the dream) and I built a nuclear bomb out of legos. The bomb somehow ended up in a missile, and the missile was one of several on the wings of the space shuttle. The entire small town I was in was evacuated, and three massive walls were built to contain the explosion. I had to climb (more like suspended with ropes and pulled up) the perfectly smooth, transparent orange colored walls to be safe. Each time I managed to get up a wall, a safer wall was built further out, and I had to climb that wall instead. The third and final wall floated in mid-air, with a several story gap between the bottom of the wall and the ground. When I was up, the shuttle was launched, the missile launched from the shuttle, and the bomb went off. The explosion seemed small for a nuke, though. In the end, the town was destroyed, the people returned, and everyone was happy.
