Nioses in my room

what happened

It was a quiet night not a car herd I was having a dreem then I woke up to feel something or someone watching me I thought that it was just
my mind toying with me then I just closed my eyes Togo back to sleep but a few seconds in I saw terrible images in my head sculls, blood , and more then I heard a screech in my room it souned like a night ferry
mixed with a Dinosaurs screech as a 10 year old girl I went under my blankets not dareing to look up then after 5 or 10 minutes I was brave enuf to look if it was gone and it was.
