A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

IN THE MIDDLE OF MY BACKSWING?!
Best way to stay sane.
This and Futurama, if I may be so bold.
Assuming you are the one conscious of the loop.
For all we know we are in one now.....
I don't even know if my memories are real
Is my life a lie?
What if last thursday I got zapped with a neuralyzer and I got brainwashed into being a depressed college dropout?
I mean due to childhood amnesia, you cant even know if your birthday is your true birthday
Is your parents even your real parents?
What if I pissed off someone and then they build a time machine and came back to fuck with me?
How do you even defend against an enemy in your future?
Also dude you gotta tell me how many loops has it been. You are the main character right?
shakes @slazer2au@lemmy.world violently TELL ME!
You had to mention Thursday didn't you.
You had to mention
Or did I?
Vsauce music intensifies
My favourite was in Orange, a Japanese series about a high school girl who gets letters from the future. It's revealed in the first episode that the letters really are from her and her classmates in the future, who are trying to prevent the death of one of their own.
Why is spoilers, so...

They ultimately fail to change history; however, they also achieve the intended result. In the past, the guy is saved. However, this does not affect their reality; it only creates a new future where the guy lives.
I'm not sure if any other time travel story does it quite like that, I'm sure it isn't unique to Orange. My favourite film, 君の名は。(your name.) sort of plays with this concept, but you really have to watch it a few times to figure out the timeline(s), and it's not really meant to be taken that seriously. Some of us in the fandom do, though.
The problem is, everyone of those movies has a different answer. Or, even worse, none at all. Looking at you Groundhog Day, become a better person... I don't think so!
Groundhog Day is probably the most benign form of time travel to get stuck in, though. So many others the thread of reality starts to fray.
I'd take Groundhog Day over a Donnie Darko or Primer situation any day of the week.
Wake up.
Again.
Every day feels the same.
Same boring routine. Same vapid people. Same dingy places. Same tasteless food.
Stuck in a time loop but somehow getting older.
Every day.
I still love the part of Haruhi Suzumiya where everyone's stuck in a time loop for several episodes. Like each episode is the exact same with maybe a couple shots being at different angles, but one line changes to tell you how many loops they've been on.
What happens if you enter a timeloop with rules that are dissimilar to the movies and tv shows you've seen?
Its like the Historical records from Galaxy Quest!
