I'm fond of sleeping the most but scrolling on the phone has become something of an issue. Staring at the ceiling moreso and I've now started to watch films on my phone before bed. Absolutely hedonistic and rotten behaviours. 

I think this is obvious

Me and my gf play Switch 2 from time to time but usually there are some better activities to be had there

And laying on your back watching Lord of The Rings.... 😒 you can do that for nine hours.

This should probably be in the NSfW section instead, but besides that, sleeping is great. I just do that way too little, because there's other great things too, and I can't do them if I'm sleeping. Also, I don't see why I'd be doing much else in my bedroom, it's not like there's a lot amenities there, and I wouldn't want to kill my neck by e.g. using my phone there very much.

Popcorn and movies - and i do mean popcorn and movies, not the "netflix and chill" thing, tho thats also pretty up there as well obviously lmao.

I mostly use my bedroom to hide from my children

Other than sleep, take a wild guess.
And yes, I often scroll on my phone before bed, read sometimes too. Or watch some videos.

Sleep and taking cover from the winter cold.

Sleep.

The older I get, the more I realize that sleep is fucking amazing, just drifting off all cosy and warm, or waking up early and realizing hell yeah, I still have a few hours left and drifting off again.
