every saturday i have home planet sickness

most of my dreams are weird. me flying is a common thing, even when im quite sure it's against the sandman's predetermined script. i once had a dream where the world was ending and the only way to stop it was to speak a word written on a cave wall. i have since forgotten what that word was so sorry, world. another unforgettable dream i had was what i called the loop where i kept waking up into a dream (predating inception by more than a decade), the scariest nightmare i've ever had.

anyways, the one i had last is right up that alley. in the dream i slept and dreamed another dream that was somehow connected to the first layer dream, and i was discussing it with someone i cant remember who. but the one thing that latched on to my consciousness was what was written on the shirt i was wearing which i saw when i faced a mirror (which is weird in itself because even though i was facing a mirror, the words weren't backwards):

EVERY SATURDAY I HAVE HOME PLANET SICKNESS

to me, it's a year's worth of wtf. i'll never know how my brain came up with that or where it picked that up. first thing i did when i opened my eyes was get up, of course, and then turn on my father's laptop, sit on the swivel chair, click the chrome shortcut and search the exact sentence in google. zilcho. so i sought refuge in reddit and asked for help. first reply i got was the most obvious explanation: you're an alien. well, im not. some said it could be a mnemonic thing like every good boy does fine. some said, in support of the alien theory, that saturday means saturn's day, and so i have home planet sickness on that particular day because my home planet is saturn. some said it's the result of my brain just putting a bunch of subconscious data together, which i already know.

overly long sigh. i guess i'll never get a definite answer to this riddle because i think that would mean trying to make sense of the mysterious ways the brain works. i just thought maybe it was something that already existed and my mind just plagiarized it. i'll be content with knowing it was an original subconscious creation.

p.s. what im quite sure of is im gonna have that printed on a shirt. yeah.
