A little while ago after doing the WBTB method I had what I initially thought was a lucid dream but that now think might only have been a semi-lucid dream.
What happed is I realised the time-frame/context in the dream was not correct – and that I couldn’t remember how I got from A to B or what had happened before. Then I knew I was dreaming and things seemed to go into focus.
I could control my thoughts and think about what I wanted to do and where I wanted to go but they had no influence and I was stuck in the same place.
What I find interesting is that when I tried to move around I was very aware of my limbs feeling very heavy – it felt like I had iron chains around my wrists and ankles.
Is this a common sensation and why might it be? Was it that I was identifying too much with having a physical body? When I shouldn’t have actually needed it in the dream?

Also is it true that if you have a fully Lucid Dream you will know 100% and there-for any time you question if you actually were fully lucid you didn’t have a lucid dream?

Thank's in advance for any thoughts and advice ^^
