Not really going to sleep well when ghosts keep showing up and waking you up every hour to show you your past, present, and future.

Just buy some for them too and sleep together
- But the three then they also get confronted with their ghosts for the past, present and future

What's the purpose of a night cap? Like why would anyone want to wear a tall, floppy hat while they sleep?

To keep your head warm during sleep.
- Does a tall, floppy hat keep your head warmer than something that lays closer to your head?
I actually wondered the exact same thing when I posted this and searched it, it's to keep your head warm and your pomaded hair off the pillows back when effective heat and regular showers were less common.
It's a statement. Similar to a thinking cap
ever tried sleeping in the cold?
- But why is it tall and floppy? Why not just like a knit beanie?

My recipe for good sleep :

AC : set to 16C with high fan speed.
Clothes (optional) but preferred naked.
A glass of warm milk.

When my child was young enough that they couldn't talk but could express themself, once I put them to bed and told them it was time to sleep. They squinted their eyes to pretend they were closed and said "honk shoo, honk shoo."

I was flabbergasted. Turns out their mother had taught them that as a kind of meditation to progress towards sleep, but I didn't know that and briefly thought they'd manifested it on their own.

Little kids are so funny with this kind of thing. They'll go from these useless uninteresting helpless little blobs, hit you with a sudden flash of personality, then just sit there and smile/ giggle at your dumbfounded face
