This experience took place in the late 1980's, while I was working as a secretary at a business firm in Los Angeles, California. I had been working at that location for awhile, and was rather comfortable with my daily work routine, albeit somewhat dull and tedious. The office environment was very professional, my co-workers were older than me and quite conservative. I mostly worked by myself at the front reception area, especially in the late afternoon when there was very little going on.
One afternoon, before closing up the office, I was sitting at my desk working on some filing when something caught my attention. The office front doors which were heavy glass and steel, began to rattle. I didn't really give that much thought, but I decided to get up from my desk and go secure the doors since it was so close to closing time. As I crossed the room to lock up, suddenly one of the glass doors blew open, and 'something' came into the foyer. The door that blew open was now shut (on its own), and what I saw just a few feet in front of me made no sense. In the middle of the foyer was a swirling, glowing green, mini tornado (dense, but somewhat see through). It stood about 3 feet tall on the floor, rotating constantly. The air within the room had changed, feeling sort of prickly. I realize this sounds very weird, but this is what I saw and felt. It moved slowly across the floor toward me, before disappearing completely; the entire incident lasted maybe 20 seconds. Once I got over the shock of seeing that thing, I ran over to lock both the front doors. Was this my imagination playing tricks on me? I said nothing to any of my co-workers about this incident because I didn't want to face any ridicule, or be dismissed from my job...
The next day, before heading off to work, I decided to have one last cup of coffee with my husband. After we settled on the sofa in our living room, I recall scrolling through tv channels, and then hearing a sudden loud popping noise. Then from beside the entertainment center (tv/VCR/stereo area), appeared the whirling, green mini tornado thing! I couldn't believe that I was seeing this thing in my own home now! Except this time I wasn't alone, my husband was seeing it also. I felt completely creeped out by its presence. I remember jumping up from the sofa and spilling coffee all over my lap. My husband had a look on his face like he was in total disbelief; I could sense that seeing this thing freaked him out too! Again, within seconds, it disappeared into thin air. Thankfully, that was the last time I saw the 'mini tornado' anywhere.
At the time of the incident, I don't recall any windows, or doors being left open in that particular room. Nothing seemed unusual about the weather that day, and nothing seemed off-kilter in our home during that time. Honestly, I couldn't figure out why I was seeing this strange thing? The internet didn't exist back then; we had to delve into the local library's paranormal/occult section for possible answers. We did a lot of reading, but never really found a solid explanation as to what we experienced (perhaps we weren't reading the right material?). All that I was left with were questions: why was I seeing this thing, and wth was it?
