People who were in a coma, what was that like? Did you know you were sleeping?

Wasn’t in a coma but technically died on operating table. Being revived was incredibly painful, I remember the feeling our my senses/feelings coming back as agonising. It was like being woken from the most comfortable and deep rest you’ve ever experienced. Awaking was like travelling up from a dark comfortable space towards a white/bright point that was consciousness. It was like refitting into your body. I actually thought I was trying to return to sleep and felt painfully angry they were awaking me. It was only after someone told they’d revived me I realised when I was awaking from.
