Back in 2009, the musician who goes by the name “Cheesy Nirvosa” began experimenting with ambient music, before eventually launching a YouTube channel where he “composes longform space and scifi ambience.” Or what he otherwise calls “ambient geek sleep aids.” Click on the video above, and you can get lulled to sleep listening to the ambient droning sound–get ready Blade Runner fans!– heard in Rich Deckard’s apartment. It runs a good continuous 12 hours.

You’re more a Star Trek fan? Ok, try nodding off to the idling engine noise of a ship featured in Star Trek: The Next Generation. Mr. Nirvosa cleaned up a sample from the show and then looped it for 24 hours. That makes for one long sleep.

Or how about 12 hours of ambient engine noise generated by the USCSS Nostromo in Alien?

Finally, and perhaps my favorite, Cheesy created a 12 hour clip of the ambient sounds made by the Tardis, the time machine made famous by the British sci-fi TV show, Doctor Who. But watch out. You might wake up living in a different time and place.

For lots more ambient sci-fi sounds (Star Wars, The Matrix, Battlestar Galactica, etc.) check out this super long playlist here.
