Hello, this is my first post, here is a story of what happened today, I'd like to hear the opinion of anyone who's experienced in it

It was afternoon, I haven't had much sleep last night so I decided to take a nap, after laying down for couple of minutes I felt asleep. I've had a dream that I talked with my friend about topic of lucid dreaming (now aware I was dreaming it) and it was quite long and clear dream, at least it seemed like it. When I woke up, of course then I realized it was a dream, so I started thinking about it, how strange that was (talking about dreams in a dream part) I was still laying in bad and very sleepy and tired, because I woke up just a minute ago. I decided to have some more sleep, still closed my eyes still thinking about it, then as I closed my eyes and started relaxing I started hearing vibration alike sounds (similar to Alpha and Theta vibrations) getting stronger and stronger, also pressure in my ears and chest which was also increasing each second, I couldn't open my eyes or get up, everything was black, but I still could think (it wasn't like sleep paralysis which happened to me once, this was a kinda different and was happening while I was falling asleep instead of awakening as in SP) , I got a bit scared as the feelings got stronger and struggled to open my eyes, I succeeded, then even more struggle to move myself. I was awake but still really tired, I had this feeling couple of times before (every time it happened when I tried to go sleep again after waking up from a dream) but always fought it, never relaxed and got to it deeper. As I was still tired I tried closing my eyes and going back to sleep, but the same thing happened and I had hard time fighting it again, it happened couple more times in the same sitting.
Then I got pissed and got out of the bed. What I think happened is as I woke up from the first dream, my brain was still in the dreaming state, when I tried to go to sleep again, still thinking about the dream my had, I was starting a lucid exchange of the waken and dream state. If I followed it and not fought it I would have started a lucid dream perhaps.? what do you think
