This case is very suitable for the phenomenon of a time loop. You can read more about such cases in the article "Stories about people getting caught in a time loop". However, this may be associated with the curvature of space or even with penetration into another dimension.

“On May 20, 2018, my dad, my mom, and I went to a Baptist church in New Jersey. My baptism was scheduled for that day, and my cousin, who works as a preacher in this church, was to conduct it. We ourselves do not live in New Jersey, but we agreed to this church, since it was only a few hours away from us.
The trip went as usual at first, my mother often travels to this church and always takes the same route. True, I cannot tell you the highway number, I always remember these things badly. In general, my mother knows the path from us to the church by heart, and just in case she has Google Maps on her phone.
And suddenly everything changed around. The highway itself, as it was just a straight road, remained, but now there were no exits, no places to turn, there were no buildings in the distance. In addition, the sky and trees have become grayish and not the same as it happens during the rain or before it starts, but such a gray color when the photo is discolored.
I also noticed that it became very quiet and the engine of our car also seemed to run much quieter than before. I looked at my mother's phone in Google Maps and it showed that we were driving along a completely straight section of the road and there were no objects nearby.
Then I noticed another oddity, the rest of the cars disappeared, we were driving all alone. In this state, about 15 minutes passed and during this time I did not see a single car. Then I noticed that my parents understand that something is wrong here. Mom said that she probably missed the exit from the highway, and dad said that he followed the road and had not seen a single exit for a long time.
After that, we spent a few more minutes in oppressive silence, and suddenly I finally saw one car in front of us, and then another. And right there, along the edges of the road, various buildings began to appear, and there were more and more cars. Soon we noticed an exit from the highway and drove on in a completely normal environment, because the color of the sky and everything else also returned.

Later, I tried to talk with my parents about this case and repeatedly, but they did not want to talk about it and it seems that they were completely confused. My father did, after several of my attempts to talk him about this incident, began to switch the conversation to another topic.
I came to the conclusion that something on the highway seemed to turn us off from reality, and if we had not been brought back, how long would we have been driving along this endless highway? And how did we slip into this “point”? And if we had not pulled out, having finally seen the exit, what would have awaited us at the end of this highway? Maybe then we wouldn't have returned to our world at all?
This has become my biggest fear. More than a year has passed since that trip and soon we will have to go again to my cousin in New Jersey. On the same road. Now I am afraid it might happen again."
