This happened to me as well, I have some footage of me walking around with my friends while unconscious.
This is what happened to me:
I was sick so i was losing blood, and i lost consciousness. I knew about the bug to press esc to see while you are unconscious, so I navigated my friends to my body.
friend 1 handcuffed my body and defibbed me(we dont know what defibs do, so we tried it) the defibs did not wake me up.
i then figured out i was able to walk while unconscious, so we were all having a laugh about my dead guy walking
he gave me a blood transfusion and i woke up.
