Welcome, congrats and yes

Welcome to the forum rockinred and congrats on the lucid dream. Yes, it is possible to have a lucid when napping. Some of the most vivid lucids can happen when this happens. You usually have to be really tired and worn out for it to happen though.

I almost had a lucid nap today, but I wanted to watch the end of a film, turns out the lucid nap would've been more interesting
