so i have been learning about lucid dreaming for about 2 months now and ive actually had a decent amount of sucess, i usually remember 3-4 dreams per night now and i remember alot of information in the dream, i do however have a problem.

In almost 2 months i have become lucid about 5 or 6 times, the thing is though, everytime i have become lucid, it is NOT because of dream signs or reality checks, it is simply because i have just realised im dreaming, for example, i have just been walking down a road and realised im dreaming, i didnt even have to perform a reality check i just knew 100% that i was dreaming then i started to fly around

it seems to me that by just thinking about lucid dreaming and writing down my dreams has helpled me to become lucid.

why is this happening? why am i not recognising my dream signs then becoming lucid?
