Seeking guidance during Laylatul Qadr

Assalamu alaikum, brothers and sisters. I can't fast this Ramadan due to health reasons, and today marks the fourth day of Laylatul Qadr. I still want to do what I can, like dhikr and listening to Quran recitations, but I also want to make dua. Here's my situation: since Laylatul Qadr is after Isha until Fajr, and I don't have a private room (I have to keep it discreet for personal reasons), what I do is go to bed and silently talk to Allah, making dua until I fall asleep. Is this acceptable if I'm not sitting up formally? Jazakallahu khayran for any advice.
