Weird brain thing

Anyone have those really weird spikes of imagination at late night? Currently writing this in 12:15 am, and I have millions of ideas for diferent things. And I also imagine those scenarios you make where you have powers or some crap like that. I never get these in the daytime...

Apparently, since you're getting sleepy, your brain starts doing less motor things, so it starts to think a lot more. And there comes the imagination and creativity. No distractions can also come into play. Anyone know how to activate this type of creativity at daylight? Because my keyboard sounds really loud.
