I Keep Having This Dream

I rarely have dreams that are exactly the same every time I have them, but this one is one of the few exceptions. Honestly I am a little worried and I don't know how to feel about it. It is an oddly specific dream.

I am in a 7-Eleven parking lot, just outside of a jet black van, fueling it on the right. For some reason it has two fill ports: one on the right and one on the left. I can only fill it with the right port though, I am scared of the left one. I don't know why.

As I am filling the van, I am watching the flip displays on the pump slowly turn over, seemingly endlessly filling the van, it always finally stops at 30 gallons of diesel, 93 dollars. I take the hose out and close the fill port, get in the van, and get right back out to see if I actually removed the hose... I did. The gauge still only reads a quarter tank...

I get back in the van and close the door, a sinking feeling setting in as I do. I am terrified, I don't know why. I turn it over and start driving, getting onto a highway. Route 70, speed limit 65. I speed up to 75 and enable cruise control, thenlook around my cab, feeling scared.

The longer I drive the louder the engine seems to get, around 120 miles in of just non-stop driving the needle suddenly drops to empty and the engine stalls. I pull over, feeling like there is something watching me. I put 30 gallons in... I thought the needle was just wrong... Why did it stop...

Shaking, I open the door. There is an odd smell, Ozone. I step out of the van and see myself fall forward, no longer in first person. My body lays there lifeless.

I wake up. Why?

Why did the van have two fuel ports? Why was I scared of the one on the left... Where was I going? Why didnt the tank fill? Why did the needle just suddenly drop... Where was I, what killed me? Why could I see myself dead on the ground..? Why was the engine getting louder? Why route 70? JUST WHY?
