Late Night Noises

At 4:20 Monday morning I was woken up, by something.  Could've sworn is was a loud noise but after some investigation I couldn't find any evidence as to what it could be.

So, without something concrete I've been forced to make some guesses. 

Here's a few things that might've made the noise that woke me up.

Crazy Homeless Person 

I know Sheboygan doesn't have a very large homeless population.  There isn't people sleeping on sidewalks or anything but I did spot a person snoozing in their car this morning.

 Destiny the Cat

She may look innocent enough but believe me, it's possible that this feline has a grudge against me.  Maybe it's from that time she snuck out on the deck and I didn't know she was out there until the next morning.

Paranormal Activity Entity

I know it was only a movie but spirits do exsist and who the hell knows what might be roaming around my apartment in the middle of the night!

And finally.

This Guy

I think that's the scariest possibility!

So, what do you think?
