Uncertain

I’m unsure if what I experienced last night was accidental lucid dreaming or what but I’m looking for some advice. Now I could just be over thinking the whole situation and it was just a nightmare but basically I was dreaming that I was dreaming. I’ll say dream 1 (my initial dream) and dream 2 (my dream within a dream) now In dream 1 I was stuck in a cycle of getting followed and killed my some kind of demon or monster in dream 2. The demon was following me and murdering me in dream 2 and I kept waking up and falling back to sleep everytime this happened in dream 1. It got to a point where I sort of became self aware that it was happening and started to find ways to kill myself in dream 2 because I knew it would end that dream. However I couldn’t wake up from dream 1 and was just stuck in this constant cycle of going into dream 2 and different situations. but I was also fully aware that this was happening. I know this sounds really strange and not sure if this even makes sense but when I eventually woke up from dream 1 in real like I was like frozen solid and couldn’t move for a good few minutes. this ‘demons’ face has been stuck in my head all day and this situation has been playing ok my mind. does anyone know if this is something I need to be concerned about?
