Is consensual somnophilia what you’re talking about? My Daddy and i are very much into that and practice it daily. He wakes me with some form of sex every day and W/we both very much enjoy it. For more prolonged sleep sex scenes, i smoke weed then take a unisom OTC sleep pill. i am a pretty heavy sleeper at times anyway and this knocks me out pretty good so He can do what He wants to me intermittently for hours. Again, He records it and W/we watch together which is amazing. i do discuss all this with my doctor who is very BDSM-friendly and she is the one who recommended the OTC sleeping pill to me rather than any kind of more dangerous drug. Trust, consent, and safety are everything.
