noises noises noises

it's probably just the outside making noise,but it's making me anxious,i hate it,why is sleep so difficult,sometimes it doesn't even need a reason to suck,it'll happen for like two weeks at a time i'll struggle to sleep and then i won't for a bit and then it'll come back,this is unconnected to the creatures and the nightmares,the creatures are what i described to be standing/looming over me as i try to sleep,nightmares are nightmares not much to explain and this is just me not being able to sleep for no reason.
