I have noticed that when I do something exhausting, I often sit at my couch, thinking about stuff. During these activities, I suddenly have an experience that feels like I lose consciousness for a second.
The audio goes all noisy and distorted, and the general experience feels like how a dropout on an audio tape would sound like.
However, the experience jerks me to full awareness, and I then realize what happened.
Could this be some kind of WILD-like transition? I know I often fall asleep when I get exhausted like this…
