Getting confused after nights of drinking

So recently a couple of times I’ve been out drinking with mates and they’ve been pretty long and heavy nights.

I’ve had a couple of freaky moments where I’ve gone home alone and passed out but stirred in my sleep or woken up confused thinking my mates were still with me even though I went home alone.

I’ve woken up talking to my mates who aren’t even there.

One time I was actually looking around my apartment like where the fuck did he go?

Am I just so wasted at that point that I’m forgetting or getting confused or is it a bad sign?
