At first I thought the red and white voices were one person's inner turmoil, but ive been watching a certain anime lately 🤵😈 which now has me thinking the unhinged theory that the white voice summoned a demon (red voice) during a crisis but now they are tied.
theory: the white text and red text are different people. i think the white text guy (mc) is visited by a spirit (bloodmoon) bloodmoon convinced mc to stay in some sort of liminal space purgatory mc wants to leave but cant so yeah
i think "the house" is metaphorical because in the 5th video it says "we are in the same body" so i dont think its an ACTUAL house but rather the body is the house
and also in another video theres a pink text, which sure could just be the red text, but it didnt act like the red text / bloodmoon i think the pink text is a mix of both of them which would make sense because red + white = pink
theres also blue text and purple text blue text is most likely a doctor because they say "have you been taking your pills" and purple text is probably a parent / guardian because they say "bloody", which kind of implies a closer relationship
