"This happens sometimes, you see most people when they go into comas... their imaginations become over active and lead them to experience a surreal world. However very rarely... they actually do experience... real situations and it's almost as if they live a second life outside of the coma, with real people but it is likely that the situations were fake. For example a super hero in your coma state could be a farmer in real life, and that must be what's happened here." "S-so you mean... he's really out there?" "yes, Killua is real"
