Ghost On The Hollywood Hills.

I am sure that every city on Earth has been involved with ghosts stories...
On the Hollywood Hills, there is this cute property covered in vegetation that has its own "guests"...
This building has been edificated in the 1920's and I am sure that some of the after-war guests, still wander around.
In the apartment where I live, when I moved there (14 months ago), I found an old, empty pack of cigarette: I do not think it was a "common" pack, it is a fabric cotainer (really old and in bad conditions) on which there is printed "Cancer Holder,1920"... It gave me the creeps...
But this is not the principal topic I wanted to report.
In the same property, once I was invited by a neighbor of mine to go and have a drink in his house...
There were more or less 12 people and a dog... That dog was pretty excited and everytime you went there to per him, after a while (as a game) he tried to bite your hands.
I went to talk to my friend and while I was talking to him, I felt something biting my leg, right behind my knee and I immediately thought of the dog; I turned around and the dog was quite far from me and it couldn't be him! So I told my friend: "Hey! Something just bited my leg!!!" And with no surprise on his face he replied to me: "Oh, don't worry, it's just the ghost!".
Now that unit is empty, but maybe the invisible guest is still there...
