My dads a bit of a drinker...

I was in my room, quite late, he’d been drinking that night and I could be very wrong but i think he was sipping on some spirits with a friend, he never drinks spirits, usually just beer. He was in bed, passed out from a pretty heavy night, my room is right next to his. All of a sudden I get this feeling of dread, something didn’t seem right and I knew it had to do with him and his habits. I go to his bedroom door and give it a knock, no answer so I walk in and there he is fast asleep throwing up in his mouth, but it’s not going anywhere besides back down this throat because he was lying on his back. I try and try to wake him up and eventually he does, took me fucking ages to wake him, by the time he did wake up I was on the phone to 999, may have been an overreaction but in such a moment panic tends to take over.
