Try reading a book, or watching a movie.
Ok so I'm in bed and I'm bored. Cant get to sleep and leaving my bed is out of the question. What should I do?
Watch a good movie or get something to drink like a nice cold glass of milk.
Try putting your phone/tablet in another room.
Yeah I just play games on my phone or go on Twitter or Facebook in this instance. Or I might try and read a book but very rarely.
For something a little different, go to YouTube, search for "Recorded Books" and listen while somebody reads you a story.
But, a word of warning. Not all the recorded books on YouTube are complete. You'll need to be selective.
