A while ago I had my first lucid dreams what I want to know is it normal to remember falling asleep before them I've have looked all over Google for information on this but I cant seem to find anything ill try to describe what happened.

So I was in a normal dream when I realised that I was dreaming, I don't really remember how I realised but I did shortly after this I woke up I was awake for about 10 seconds being completely still, It felt like the back of my head was going numb or getting hot I felt my eyes shaking like crazy this went on about 5-6 seconds, Then I felt my conciseness fade away it was a very strange feeling it was like being unable to think like when you forget simple words you know off by heart or forget something that you just thought of but it was for anything your tried to think about.
I don't know how long this went on for it seemed like 10+ seconds but it could have been longer, after that I woke up in the dream from being asleep in the dream it lasted about 3-5 minutes, then I would wake up and the same process would happen again this went on 3 times every time was the same I remember every time I fell asleep after the first normal dream each of the lucid dreams lasted about 3-5 mins.

This was about 3 months ago and I still remember it all like it was yesterday I have had no more since then I wasn't trying to have any when I had the first 3 but i had read up on it quite a lot before hand.
