Yeah writing down my dreams is hard for me too especially when you just woke up in the middle of the night. But i found that it helps if you don’t write it down in every last detail. I only jot down a few keywords when I wake up and that usually works, then I can flesh it out it later in the same day when I have time. Takes less effort. If you don’t remember - guess, that’s a good exercise too! Don’t do it tomorrow though, never works :'D Also it can help if you’re forced out of the bed somehow for a couple of mins (drank too much water and have to go to the bathroom, for example), then just take your journal/phone with you. It also helps with WBTB (wake back to bed) by the way.

I don’t know is links are allowed but here’s the forum with fun dream tasks I mentioned: https://www.dreamviews.com/tasks-month-year/

I don’t read a lot of forums but this one motivates me because users create this witty unexpected tasks I could never think of myself. And you get to feel accomplished when you finish them XD

Really like most of the hobbies from comments, you guys are interesting!

Mine are (I’m not sure if they are niche but):

Fountain pens. Writing with them feels very nice and smooth and it’s a little piece of “retro” even though I don’t have time for any other kind of “retro”

Lucid dreaming. It’s an exercise of control over your dreams and a chance of doing something you like when you sleep. Or experience something new. There are forums with quests like “go to an art gallery in a dream and explore what your brain can give you as a painting” or “build yourself a dream homebase with all your favorite pieces of dreams from childhood” or “jump into a chalk painting and describe your experience”
