The nose-pinch test is based on sound logic, and so the only trick one's brain can pull on you performing this test is to explain away why you can breathe through a plucked nose, right?
Well I had a dream a while back in wich I was lucid and did the test anyways - and couldn't for the life of me breathe through my pinched nose. I was very confused about this, especially since I still had no doubt that I was in a dream at that point. My clarity faded later on, but that had nothing to do with it.
Two explanations that won't do are a stuffed nose (I didn't have one before going to bed or after waking up) or sleepwalking (the last time I'm aware of doing that was over 10 years ago).
Do any of you guys have an Idea what in the world happened there? Let me know your thoughts!
