I have dream signs, but this one has only happened twice and each time failed.

Its when something electronic doesnt work. Like when i walk around the house flipping the light switches and none of them are working, and i wonder if i am dreaming, but dont become lucid.
The second time was when the volume dial on my keyboard wasnt working, and again i wondered if i was dreaming, but the dream felt so so real i kind of convinced myself i wasnt dreaming. I turned back to the volume dial and when i used it it worked.

I dont know if its me or the sign (probably me) but each time i wonder if im dreaming i never actually become lucid.
