Okay I don't remember all of my dream,but I think I(or someone else was..I don't remember who it was.I might of not even been in the dream..)was in this video game and I/someone was in this creepy cave.And I/this person had to beat these bosses.I/this person had beaten some bosses.Everytime I/this person had beaten a boss,I/this person would fall into this room in the cave where these zombies(they looked like the zombies that were in this video game I played before.)that were pushing me/this person and they made this creepy noise.I/this person always had to get out of the room by opening this door that leds to the main entrance so they wouldn't bother or kill me/this person.In the main entrance,there was some lava and a hippo.The thing is,I/this person couldn't get out of the cave.I/this person was stuck in the cave and the same repeating thing happened over and over(you beat a boss,fall into this room with zombies,and then,you have to get out of that room before they start trying to kill you and return to the main entrance.)What does my dream mean?

Maybe your life is feeling a bit repetitive at the moment, like a boring video game, as if you seem to keep coming up against the same struggles over and over again?

maybe..It's so true that I have been facing some of the same struggles and issues over and over,but I don't think I was even in that dream.I think it was someone else that was in my dream.I don't know who though..What does that mean??

It doesn't have to mean anything exactly if you're not the main person in the dream, if it's more like watching a movie. It's sort of a subconscious way of getting you to look at things in a different way, as if you were a different person. Or, in some cases, it could be that you feel like a different person in waking life because of new things that you're doing, stuff that you never did before, and the dream could be a reflection of that.

I think the detachment idea, not sure it was you, may be backed up a little by the dictionary entry for zombies too:

Though you have to bear in mind your dream images can be affected a little by playing video games, if you were playing them right before you went to sleep.

well,this was when I was younger(when I was in 4th or 5th grade.or something like that) .I don't remember when I had this dream.I do remember me playing video games a lot.And I didn't really feel like a different person then because I didn't do anything different before.But I guess you can say that all changed in the 6th grade..A lot of things about me then had changed.So,I guess my dream was trying to tell me that I was going to be a different person later on in life.Also,I think I do have some emotional issues now,but I didn't really have any when I was younger..I guess my dream was also trying to tell me that I was going have a lot of things later on in life that was going to be hard to deal with.I understand this dream a lot better now.Thanks,I really appreciate it.
