i think with everyone discussed we can come up to a few conclusions
1. chris is lonely
2. chris is bored
add that he puts way to much weight into his imagination, an imagination where he is a hero and validated and celebrated.
chris would rather stay in his dreamland, but even just facing the real world as is would be too much.
chris imagines and wishes really deeply his imaginary friends were real, because the alternative would be to move on and make something of himself.
he has to believe, otherwise he's just sitting in his room clinking two lego together going "ha ha, space lesbian ponies" to himself.
