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.

Tried for at least 5 minutes to grab a book on top of a wooden shelf. Could not grab it no matter what I did- it was simply out of reach. Now I ignore things up on those shelves...
