It feels the same way when I'm waking up. Whatever I'm doing in the dream seems incomprehensibly crucial, then I realize it doesn't make sense, and then that I'm dreaming, and then that I'm awake.
The most I've hallucinated while falling asleep is occasional swirly patterns. No sounds, ever. Maybe because I've had a tinnitus for as long as I can remember? (constant ~20kHz)
Likewise, nothing when waking up. Once every couple of months or so I "know" that I've been dreaming and at best can remember a person or object from the dream. After a few seconds even that is irretrievably gone.
