I had natrural-cuased lung cancer from age 4-6
coma after being sedated: 18 days
its black, cold,empty,thoughtless
and its only when a thought sparks saying “your dead” comes you wake up........scares me......still have nightmares about empty blackness....but its not empty you can feel a feeling all around you of malevolence
-best wishes, hope I haven't depressed you
