What are vacation dreams about?

So I'm using a throwaway account for very obvious reasons. And also this happened a couple years back.

I'm a 21 yo girl and my bro is 2 years younger than me. We are very close and always have been. We go on vacations together just the two of us and generally are very open with each other about anything. I'd call him one of my best friends and I'm sure he'd do the same. We even have matching sibling tattoos.

Now in the dream we were having this really low key situation where we'd occasionally hook up from time to time. Everytime we did it, I was really annoyed with him and at numerous occasions even got mad at him. I never felt turned on for a second. The dream ended by me finding out he didn't use a condom and I got so mad that we agreed to just not do this ever again.

The dream, or anything like it never happened again since but this has disturbed me for a number of years now. I do not - in any way whatsoever - think of him in a sexual kinda way. I'm a lesbian and we both know that. I have since accepted that my subconcious mind was probably going through some emotions related to him that night (maybe we had a fight or something like that, I really don't remember) and that's why this horrible image was created but now that I've found this sub I'd like some insight into what you think caused it (and maybe any tips on how to avoid this happening ever again).

Cheers guys!

So i remember that in the dream i was going for vacation with my mom (my mom has been dead for 2 years) and i was happy. So we got there via a car i think. and it was this wiggly street with flat houses flying around it and there was a motel where my mom said I am going to stay so i went in and it was my apartment. It was all cool there was this girl and a guy. I don't remember their names. They were 20 something and chill. We went out for normal vacation stuff, but i don't remember any of it. We came back to the "motel" and i open my wardrobe and there is a hand sticking out of it. I thought it was a prank. They were smiling. I touched it. It felt soooo real. It felt like a real hand. Like my hand. The same texture and look. And i acctually felt it when i touched it. I pull it out and i look at the end of it. It was a real hand and it look like it was ripped out from somebody, but it didn't look that bad. I was scared i looked at them. they were laughing and she started pulling out a knife while he was trying to grab me. I hit him with the hand i was holding and kicked her in the face and i felt like i broke my leg when it wasn't, but i kept fighting them. I ran out of there and there was this giant who pushed me back inside to them and i had to fight them again and i woke up while beating the shit out of the guy. Weird

So basically, I had a really realistic dream where my favorite artist hadn't actually passed. I was so happy and it felt like the best day of my life. I immediately bought tickets to his concert, and then I woke up. I feel so weird right now. Like I want to break down and cry but I don't want to ruin the day for the others around me (on vacation) Can anyone explain why I feel like this or does anyone just want to talk

I had a dream where we were going to go to Italy as a vacation but it took a long time to wait so we are McDonald's then we finally got on the plane and the engine failed I also saw in third person a part if the left-wing was missing and just as it almost crashed next thing I know It's October 18th, 2018 I went about a year in the past. I basically time-traveled I was very worried and started crying telling the people I knew but my mom didn't believe me but my friend and bully did for some reason I was friends with my bully and we were in a car I told them something about the future that one teacher ends up replacing the English teacher. Anyway, I started to pray to all the gods even though I don't believe that stuff I don't remember what happened next except that I woke up in another dream and turns out I got hit in the head I was on the side of the road. I told my Mom what happened and she said she remembered me that day. Then the dream ends.

I was going to school it was the last day of school and I was talking to my mom about how it was going to be a good summer vacation and I got to school and started the day off as normal put my stuff in my locker and went to my first class of the day. But then about 30 mins into class (I didn't dream that long or anything I just knew) A zombie broke down the door into the class and starts eating my classmates. I run away and usher everybody out of the class and close the door before the zombie comes to get us. I turn around and the school is in Anarchy Zombies everywhere and people getting eaten I run to grab my stuff out of my locker because I thought I would need them. Then a zombie pins me to the lockers behind and tries to bite me. I open a locker and hit it in the face and kick the zombie into the locker and shut it. Then I grab my stuff from my locker and then all the zombies start chasing me I text my mom to pick me up from the school. I burst out the front doors of my school with a hoard of zombies chasing me I start running home because I don't know where else to run to. My mom pulls up around the corner and I get in and we drive away my family is in the car except for my dad because he is at work. When we are driving by our old house my mom says to call my dad and tell him we will be meeting him at "The Hotel" I tell him and I fall asleep in the car. Then I wake up in the dream to find out where we will be staying it is a big hotel it is taller than the clouds and each floor is bigger than the house I live don't live in that small of a house. My dad is there and so are my grandparents and somebody from school. We walk inside and have lunch. Then I wake up
