Shall I go on an adventure or stay in bed all day?

Have an adventure in your bed. It's called dreaming. Go to f*cking sleep!

Plenty of time to sleep, and eventually eternally
Go on an adventure

Staying in bed can be depressing!
Adventure! Adventure! Adventure!

Go out and get fresh air and exercise

Go camping, bring snacks and stay in your tent the whole time

Take your bed on an adventure outside.

Trust in the bed, you must.
