I often meditate sitting up on my bed as well. If I can't sleep, I do breathing exercises; mindfully scan my body; or something like that.
I think that one of the most essential points of meditation that anyone can do it anytime, anywhere—even in bed.
Best place to meditate is on a bean bag.
Depression issues aside, if you're not prone to falling asleep or staying in bed longer than you promised yourself, then heck yeah! Laying down when meditating is incredibly soothing. I do it nowadays because my mental state improved over time and things got so much easier.
Hope this helps!
Wishing you happiness and love.
To meditate in bed time you could meditate anywhere you want… It helps to get relaxed calmed and focused.
Obviously a lot of mediations are better done in a comfortable seated position – but ensure you are comfortable and not holding yourself in a position that is unnatural and/or causes pain.
