When I was about seven (maybe eight, maybe six but around that age) I dreamt that I was trying to play games on my favorite website in the middle of the night but found out that at nighttime, websites with games on them turn into "serious" websites and all the games become unavailable.
I also used to have this recurrent dream about finding out that I'd left a computer game abandoned and the sprites were crying.
I was curious and wondered if either of them were true, but didn't test either of them because with the first one, I didn't want to break the rules and with the second one, I didn't want to make the poor sprites sad.
