Alters talking when your asleep

Not very often but sometimes my alters wake me up talking at night. I can tell its them and not a hallucination. Does this happen to you?

No, never happend as far as I know

Kind of. It happens to me sometimes as I'm falling asleep. Maybe a hypnagogic hallucination but also them at the same time? I recognise them. That's my experience, anyway.

What happens sometimes here is, sometimes the one who is front-est keeps thinking during the night and keeps the body awake - but if they think while somebody asleep is front, the body sleeps.
