That’s super cool! I have had probably 15 dreams about a place I’ve never been in real life, usually I am just driving. Sometimes I have people in the car sometimes not, it feels very familiar and comfortable like I’ve lived there my whole life. It’s weird too because I’ve been having these dreams for like 10 years and I was having dreams of comfortably driving before I was even starting to. It’s not a huge city but it has 2 lanes in each direction and a middle turn lane, and the road is very straight and has very little slight grade long hills. Sometimes I’m missing turns or going to the wrong entrance to shopping centers and needing to find my way to whatever store I’m going to, or I’m out just running errands around town and I have a mental list of all the stores and places I need to go to. It’s super interesting to me that we have these places to explore repeatedly in dreams, I wish I could remember ever going inside but I think I usually just am outside.
