Had my first sustained lucid dream last night. I was in what appeared to be a large shopping warehouse such as Sams Club and when I got there I heard a message that this was a special place that people go to attain lucid dreams. There are other various people around me. I decide to look at items on the shelf with the realization that they are created by my dreaming mind and walk over to another part of the store. I then think since I'm lucid that I should try flying. I lean forward 70degrees and my legs lift off the ground and I start floating down the aisle. One of the attendants tell me not to float too high for a safety reason (she doesn't go into details). I stop by a frozen bratwurst and shrimp freezer and evaluate which bratworsts to purchase. There are also packs of frozen noodles. I didn't wake up directly from the dream, so I don't remember what happened after that.
