It all started when I was 5.I went to the backyard and saw a foot,Yes a human foot walking around in my neighbor's yard.I threw rocks at and it made a loud hissing sound.Next week I saw it again I told my dad to kill it but he couldn't see it even though he was looking right at it.My dog saw it and started chasing it.It moved wicked fast.My dog couldn't even catch it.Finally It left.I saw a word on the door that said BEWARE.If you have seen somthing like this tell me.
