No Me puedo dormir...

Its 10:00 p.m. and I can't seem to fall asleep....maybe its just que tengo miedo porque e estado oyendo ruidos en mi casa...Cucuy! No, really I have and its getting to me..I wonder what it is? Man...why does this happen to me? and it seems like I only hear them at night when i'm with someone...yesterday I heard it with my mom and today around the same hour I heard them when I was with my cuata....tengo miedo...que hare?
