The whisper in the dark

Ok to start off first my name is Travis I live in Michigan and ever since I was little like when I was possably 6 I am 15 now but when it is night I hear whispering like there are probably over 30 people in my room talking just last night there was something on the ceiling its legs and arms were stuck back on the ceiling but its torso was faceing down twards me and it was just hissing and there was this odd black mist hanging and whiping around it and then just vanished but then I began to see things on the floor hissing and yelling does anybody have any insight for me on this thanks -spiek
