I'm not sure if it was a demon that I saw but my friend was with me and he knows a little more about this kind of thing and he was sure it was a demon. As far as I'm concerned it could have been any kind of paranormal happening.
My friend Connor and I were waiting outside of a friend's house to pick him up, sitting in Connor's car at like 10pm. About 50 yards ahead of us, I started seeing a little blinking red light. I was high so it took me a while to respond or realize that that was a weird thing to see even though it was very prominent and caught your eye, and didn't have my glasses so firstly assumed it was some kind of road sign that I couldn't see properly, even though it was in the middle of a residential area I knew well. The little blinking light started to move around and stop blinking, solidifying into a red color and doing almost like figure 8 type things but was not making a precise shape with its movement. At first I did not think it was in the air, just thought it was moving farther or closer from us on the road, thinking the movement I saw was just depth perception. I asked my friend Connor "what is that? Do you see that?" and I think I said other things but don't remember well. I looked up to him and he was staring at same place I had and looked dumbfounded. He said "oh my god ya!"
The light started to get closer to ground and more spastic and then it grew tall, fading in color, becoming less of a bright red and more of a shadowy figure and swooshed to the left and toward us before disappearing. All this happened in like 20 seconds and after it was all done I started to panic and demanded that Connor drive away but he wasn't as freaked out, even though he had just seen it too, and insisted he saw it too and believed me but said to relax and that it wouldn't hurt us. I still was very creeped out and having deep feelings of fear as I sensed the thing near us and knew I had just seen something.
I was getting terrible vibes and was in complete shock and fear. I kept staring at the same spot that it had occurred and thought I saw a couple of hazy outlines closer to our car but nothing ever solidified and I never saw anything as clearly as I had seen the thing the first time. But it took me a while to calm down and even longer for the occurrence to leave my mind, but I still remember it as it happened and still have the image of it firmly in my memory
