A lucid dream out of nowhere

I am not a natural lucid dreamer, and had stopped writing down my dreams months ago. But I had a lucid dream on holiday, I use a wheelchair and in my dream I was stood up outside my house and a wheelchair in my dream was next to me, which made me think why do I have a wheelchair if I can walk, which then made me realize that it was a dream. Shortly after I walked down my drive and I started loosing lucidity.

A lot of people have lucid dreams without any practice, they just happen every once in a while though they are more prevalent in children. Chances are if you know what they are you will remember it but if you have no clue you will likely forget it until somebody brings up the subject. If you start talking to somebody and explain to them what a lucid dream is they'll probably remember one.
