Just took a long nap.
The dream:
Some friends and I were visiting a strange laboratory/hospital/private school/something? and we were perusing the exhibits and visitor things on the lower floors, but that’s not why we were there. The place was a massive front for something far more sinister. I don’t remember what the goal was, but we had lab coats and fake IDs we put on as we climbed a narrow flight of stairs towards the back corner of the building. As we reached a restricted area, our fake IDs, being fake, triggered a yellow light to flash as we passed a certain line on the floor. I chickened out even though no one was paying attention to the yellow light, because of course I did, but the rest of the group proceeded up more stairs. I anxiously paced around a bit as various actual employees passed me, paying little to no attention to me. Suddenly, a big alarm went off, warning of intruders (my brother and friends of course) and everyone was ordered to evacuate. I went downstairs and passed several young children from the school there, and a teacher was saying something about how she thought it was a grand lunch lady scheme. I made my way to the exit and went outside, only to see privately-owned bomber planes overhead, which proceeded to drop bombs over the area of the building where my group likely was. The fat teacher yelled “Yee-haw!”
