Sometime during a low quality normal dream, I realised I was dreaming - then dropped everything I was doing. The scenery turned black straight after, and I had assumed I had woken up.

I lay in bed for a while, then could feel trainers in my hands... I knew I was lucid at that point, cause I could hear my fingers going over them and feel like they were changing form, but that was it. It felt like only my arms were in the dream state, and everywhere else was in the real world. Sure enough, as soon as I opened my eyes, the "dream arms" disappeared and my physical ones in bed took over, which took more effort to move. Did an RC, and was definitely awake.

When there's this sort of disconnection within body parts in a dream, is there any way to save it?
