Dreams, Dreaming, etc.

Sorry about this format, it reads as a 4chan green text because I just wanted to take quick notes before going back to sleep. Well, I can't sleep anymore now so here's the dream I just had:

[ Dream ]

• Go to department store, give car to valet parking.
• Do some errands.
• Go buy italian food to eat at home.
• Accidentally mispronounce it.
• Lady corrects me and I thank her.
• Pay for food with a 200 mxn bill.
• I get a 500 mxn bill and some coins back as change.
• Say this is not correct.
• Order a second serving.
• Pay with the 500 bill.
• Get the initial 200 back as change.
• Accept it for some reason but I'm weirded out.
• Go to parking lot to get in my car.
• Car is parked weird and the trunk is open.
• Look around and see other cars parked the same way and with their doors open.
• Drive out starting to suspect people being poisoned by some gas leak or something (maybe carbon monoxide)
• Driving in the city, take a left turn.
• It is a nice looking neighbourhood of apartment buildings.
• There is a median with some grass and palm trees in the middle of the road.
• There is a person lying on the ground in said median, the body is covered completely in red. Maybe paint?
• No features discernible.
• I see another "body"
• And another. Then a couple of them piled on the road.
• They are everywhere and they are in weird and contorted poses.
• There are so many now I have to reduce my speed and drive around them.
• At the end of the road, there are two people standing covered completely in red. No features are discernable.
• They are kissing passionately
• I turn back
• They are now biting and eating into each other with the same passion.
• Get that goosebumps feel you get during a nightmare.
• I wake up in real life.
• Hear a police or ambulance siren in the distance.
• Bunch of dogs start barking.
• Stay like that for five or six minutes.
• I don't want to check the clock, I know something's wrong.
• I check the clock...
• 3:39 am
• I knew it.
