Normally i get an idea in my head, then it stays there. Results of ignoring it is Resistance to sleep and an inability of that idea to leave. Doing that idea instantly like the dev ones concludes to a lack of sleep but progress being made.
I also remember waking up my sister saying it was time for school, go downstairs, have a shower, then walking in the living room in nothing but a towel from the waist down to find my mothers and farther guests that have just come over for a drink see me get some fresh school clothes. It was apparently the stroke of midnight and my excuse was that i was getting ready for school. My sister wasn't happy. the guests thought that my parents child was "Dazed and confused."
