Just recently I have been waking up at around 04:00 am and about 10 minutes before my alarm is due to go off, I find this incredibly annoying and sometimes in the weekend I wake every up every 2-3 hours or so is this a disorder , as one of my friends said it may be if it persists.
Or is it because I am not sleeping in my own room as the upstairs part of our house extension is happening in there and I am sleeping on my matress on my youngest brothers' floor?
