Can't sleep from dreams with "stressing situations"?

For about 3 nights night, I've had very strange but normal dreams. Like I'll just be at a gas station, but for some reason I'm super stressed about some semi parked there. And I'll get worse and worse til I wake up, I wake up and still fel the stress so then I feel all pissed. I try to go back to sleep but every time it's the same dream. It gets to a point where I'm tossing and turning for 5 hours, I get so pissed cause all I want is sleep but no. Please what can I do? I don't know whats causingmthis but it's killing me, I'm almost in tears right now (also, Ive had strep throat and am on antibiotics if it helps)
