Thinking(audio/visual): daydream
Clear mind: aware

put your awareness on your eyelids and secondary awareness on hearing, or any other sense.

Good luck and it's easier than it sounds, I changed on a day but I sometimes daydream although, I snap out.

Also I don't keep awareness in my room because then I get bored but I also don't think because I would get depressed; I either play videogames(aware) or lay back in music. I also like to cook and I keep awareness the whole time but I'm doing many things at once so I don't have time to think.

Read my other post about how I used to daydream. Being aware will make you more rational, activate your calculating mind & personally me it distances me from my feelings making me more apathetic than ever.
