I've been trying to lucid dream for over a year now and have almost become lucid a few times but every time something happens that destroys my lucidity, the first few times it happened I woke immediately after realizing I was dreaming. The next few times when I was able to hold onto them for a bit longer I would say "I'm dreaming!" and somebody around me would say "No you're not, you're acting retarded stop being such an idiot." and I would believe them. The last time I became lucid was a few nights ago and after realizing I was lucid I was suddenly surrounded by fog and had no control over the dream, I had to run through the fog constantly reminding myself I was dreaming. When I was finally out of the fog I tried to push my fingers through my palm but it didn't work, I was sure I was dreaming so I tried to breathe with my nose plugged but that also did't work. This combined by the fact that I didn't seem to have any control over what was happening led me to the conclusion that I was not dreaming. Any advice about why this keeps happening?
