In November 2013, my wife purchased a large zip-lock plastic bag full of religious medals and cheap jewelry from a thrift store in Stockton, CA.
We have our home computer in our bedroom, next to which is our dresser. I dumped the jewelry on the dresser and went through it. It was mostly metal earrings, pendants, and Catholic religious medals. I left the jewelry on the dresser. I was going to decide which stuff was worth keeping, if anything. My wife is a thrift store junkie and she buys stuff all the time even though we don't need it.
Within a day, I would be working at the computer and I started seeing black shapes or shadows out of the corner of my left eye. I really thought there was somebody there. I turned to look and there was nothing. This happened quite a few times.
I started to feel a tingling on my arms and shoulders. It was electric, like I was getting shocked. It made me get goosebumps and made the hair on my arms stand up. I thought there may have been a short in the electrical cords on the floor or maybe an exposed wire was touching the computer table. I looked and there was nothing. I also felt like my shoulders were being touched but I figured it was just my imagination. I really wasn't getting too concerned.
Another day passed and my wife was talking to me while I was working on the computer. She was standing a couple of feet away. A very, very strong smell of sweet perfume suddenly permeated the air. It was like old-fashioned grandma perfume. I asked my wife if she was wearing any perfume. She said no. I asked her if smelled what I smelled. She said yes. We both kind of freaked out and literally ran from the bedroom. We weren't terrified, just creeped out.
I realized this stuff didn't start happening until that jewelry was brought in the house. We thought about returning to the thrift store but we didn't want this stuff happening to someone else. I bagged it all up and threw it in the dumpster at our condo complex.
My wife and I noticed an immediate change in atmosphere in our condo. It was like a weight was lifted, the place seemed lighter. There was no denying that something was different.
Everything happened in within a three day period. I am glad I recognized it early. Our place has been normal since.
