Some time in the middle of the night last night Three of my outlets and the light in my bedroom stopped working. All were fine when I fell asleep. I checked the breaker and it's not popped. I switched it on and off and still nothing. Other outlets and a light on the same breaker are working. Why would this happen and what should I do next to figure out the problem.

I would check the 2 outlets next to each other(One that's working and one that's not)
Could be in a light or switchbox.

I'd suggest you turn off the breakers for your room, take off the plate and haul the receptacle out, take look at the terminals and see if the wires are connected and are tight, the outlets are all connected together so its worth taking a look at.
