My husband was sleep eating

So last night I was already falling asleep my husband was already sleeping. I know because he was snoring and had been asleep already for almost 30 minutes. Well I was facing up and I feel my husband sit up and get on top of me and start eating me out. I asked him what he was doing he didn’t say anything and then lays back down and starts snoring again. I should have woken him up to finish what he started but was too sleepy and confused. I then asked him in the morning if he remembered what he did last night and he said he didn’t. I questioned him multiple times to make sure and he said no. He does have a history of sleep walking when he was younger. Has anyone had that happen to them?
