I don't believe we disappear completely, Not a total reincarnation but I believe once you die you can come back but only in fragments of your old self, probably unrecognizable to your new self, Maybe in traits or feelings of deja vu.
Eating - Nothing
Drinking - Coffee
Listening - Kampfars' Hymne
Doing - Attempting to sleep
Thinking - I shouldnt be drinking coffee or listening to Kampfar if I want to sleep....
