As I was going south on I35 I witnessed two flying objects one on the left and one in the right side of me the one on the the left flew like an airplane and had the flashing lights. I knew that it was a plane indeed. On the right the ball of light was huge and too big to be a star too bright to be a plane. And it was slowly descending. I realized that it was following me. I was driving from Round Rock to San Marcos. It followed me from I35 and Braker all the way to my exit about a mile from Kyle at 210. I passed Austin Buda and Kyle. The whole time this white ball of light was keeping up. I ran out of gas and had to pull over. I was hoping it would wait for me. Amazingly it did. As I walked out of the store I spotted it in the same place I left it and it was hovering like slightly moving up and down. When I got back on the road it followed. It would glide and periodically move closer to the ground then back up but somehow it was still pushing forward. It stayed on my right the whole time. Once I exited the freeway I drove on the feeder road for about a mile before I had to make a right. At the point I lost sight. I’m not sure if it disappeared and reappeared or if I just missed it gliding across to my left. It was leaving and getting smaller. Luckily I had to make a left to get home. I wanted a witness so I called my husband and asked him to meet me outside so he can see too. I pulled up and grabbed him we spotted it and so I drove a little closer so he could see as the light was moving further away. I wanted him to see what I saw so bad. Half disappointed that it was leaving and surprisingly I started to come back. Not only that it was descending again!!! It was awesome. We watched for another couple minutes then we went home. I went inside while my husband gathered my things. When he got inside he said it was directly over our home and can be seen clearly. We brought the kids to see for a bit and went inside as it ascended back into the galaxy slowly getting smaller until it blended into the stars. I wasn’t afraid I was halfway expecting to see this. It was exciting. No one around me seemed to notice or care. This felt personal like they wanted me to see for myself. This whole event lasted about 30-40 min. And that’s my ufo encounter.
