I used to do reality checks in school it felt like I was secretly doing drugs or something... "Uh sorry David just have to uhm check a thing".
And one time he saw me and asked what the h*ll I was doing and I had to explain my "dark" secret lol. The next night I had a dream where I were in a classroom and the teacher that usually is very nice to me was suddenly super rude... I did a reality check and thought the South park line "Scr*w you guys I am going hoooooooome".

^-^ But the dream incubation thing should work pretty good as well. Good luck
