>>11654052You can imagine you pull out a revolver whenever you are stressed or bored (and flipping it or something) instead of fidgeting. When you see a bad dream you will be stressed and since you will have associated that with pulling out a revolver, you will actually pull out a revolver. A revolver can be very handy in a stressful dream, you can shoot the source of the problem or even off yourself. I accidentally discovered that, and have already killed enough monsters and people that haunted my dreams (dreams after you kill your enemies become very happy and cheerful). It's so fun as well because they never expect you to have a revolver and are always surprised by how the tables turn before their demise (afterall in a nightmare you are not supposed to be able to stop them). Only side effect is an urge to pull out a revolver at random times irl.
