My mom bought a house on the corner of Woodcrest Drive. My brother, my sister, my brother-in-law and I have all had unexplained happenings unfold in that house.
The one experience that is most prominent in my mind actually occurred to my brother. His name is "D". "D" specifically recalls seeing a gnome in one of the bedrooms circa 1994!
He told me that one day, in the early morning hours, he woke up from sleep. He laid there in bed and recalls it being eerily quiet and, just then, it felt as if someone (something) was staring at him! He turned to look towards the doorway of the room. His eyes quickly focused on this creature that was no higher than the adjacent electrical outlet. He recalls that the creature was wearing a weird, dirty sport coat. He also recalls that it had on one of those old boat hats on, similar to that of a Leprechaun. And most vividly... Was the sinister, overly-exaggerated smile it possessed!
My brother's natural reaction was dictated by the intense surge of fear that ran through his body! He quickly sought security under his blankets and turned to face away from this thing! He did try to rationalize to see if whether or not what he saw was actually, physically there. He said it took all his will and might, to turn his attention back towards the doorway--and there it was again! Motionless. Sitting perfectly still, and with the same sinister smile!
The night carried on and the sun's ray did make it to his bedroom eventually. It was only then that he made an attempt to find this creature - it was nowhere to be found.
My brother ended up tucked under his blanket, unbelievably frightened, until the next morning! Neither of us have any idea as to what it was that he saw. I've heard folklore of gnomes and, the more I think about it, that's kind of what it sounds like.
In this same house, I myself would often hear footsteps upstairs as if someone were walking... Yet, I'd be the only one in the house! I would fall asleep on the couch in the living room, only to be awakened by a loud, muffled clap right next to my head! (Kinda like open-hand slapping the cushions of a couch.)
Presently, the occupants of that house also experience paranormal activity! I, too, am curious as to the history of South Ridge (Fontana, CA). Don't know if public records were properly kept for that area.
Thank you for reading!
There are also quite a few ghost stories - some better researched than others - reported in the area, perhaps if one is very near to you, there might be some connection with your experience.
Another article pointed to KKK activity - anything that causes such charged emotions, anger and fear can lead to activity as well. Though, I don't think the gnome would necessarily be connected.
