Weird nightmares I have been having lol

TW// car crashes

so I just got my first car a few weeks ago [I was very privileged to get my first car at 17 as my grandparents had saved up for it over the years]

Sense then, I have had nightmares about me crashing the car in some way- one nightmare was at school where I had backed up and all of a sudden cars had appeared out of nowhere and I [somehow, despite my car being a 2011 Buick] had went over the other cars behind me.

The most recent one[and by recent, I mean last night] I had a dream where I was going home from Walmart [I havent driven there by myself yet, I've been too scared to sense I have to drive down a mountain and doing that by myself scares me] and I truck clipped me on the side, causing me to drift to the side of the road- crashing into a tree which caused the car to roll over.

Any tips on stopping these dreams? They've caused me to have more driving anxiety, for example today I was planning on going to dollar tree to get some jars, candles and some ground sage but I haven't gone anywhere sense the dream I had sort of scared me.
