Can you do it?
I hadn't been able to for about 4 or 5 years, then seemingly out of nowhere a few days ago I became able to somewhat regularly gain cognizance that I was dreaming. I was not able to change anything as it was more a passive awareness that what I was experiencing was not real and simply allowed me to act in accordance; basically like playing a video game.
A couple nights ago I had a dream that I was riding my own bike on the freeway when a cop on a Harley lit me up from behind. I was thinking about what to do when it occurred to me that something was
off, most likely because I was dressed like a squid

I thought, "hey, this is a dream, real-life consequences wont' apply." So I took off

Epic high speed chaseness.
Is there a particular key to gaining complete awareness or is it just luck? Are some people naturally better at it? I've found that despite a questioning nature I have a very active personality trait called "absorption" and IMO it makes me accept dream reality more strongly.
