Recurring dream settings but different activities inside the dream.

hello everyone this is my first post on here..well lets just get right to it..the reason i am coming to post on here is because i remember certain details about my dream so vividly and they are so different from any other dream I have had so id like to see some opinions on what maybe you guys get from certain things inside ..the night before last i went to sleep and started dreaming...

I was brought to a house..in a neighborhood that was kind of like a typical suburban neighborhood decent sized houses nice front yards and alot of grass and just a nice place..I dont remember who brought me but I was brought to an older man and older womans house id say around the ages of 50+ but i rememeber greyish hair..as i enter the house i dont know why i am there but i see a few friends of mine..random people i have known throughout the years and i remember the old man making us draw on these papers certain symbols and after we finished making them we(3 or 4 of us) had to use super glue to put around what we made...kind of like a shitty laminent..then he had some needles filled with some kind of muscle relaxing drug id compared to something like heroin or that..and i remember he got me with it and i didnt like the fact of the needle going in me and i wasnt so drugged that i couldnt move so i eventually realized what he was doing and had to go help the others..so i managed to wrestle with the old man and stick him with some of this drug and he got knocked out cold i went to gather the others. i gathered them then i realized the old man might have woken up by now so i went to him and boom ..sticked him again with some he got KO. and i remember going a distance in the house which became a bit like a forest towards the back ..eventually i come to this roof of a room with a woman in it(his wife i assume) and i just down and stick her or kill her i dont remember..and then i escape the house with my buddies and that was that...the strange thing is ...

last night i had the same setting of the dream..in the same place but before i got in the house i saw the wife drive up ..and by the way it was only with one friend and this time i was very cautious to enter..i felt like i was dropped off by my parents and the old people were acting like they were going to be doing something else but no..i knew what they were up to..the wife drove up and i started to curse at her and tell her fuck off you bitch and shes cursing at me..as if we knew eachother i said i remember what u did you asshole ..i was extremely mad becuase last night in my dream i remember she was trying to stick me with the needles...so me and my buddy continue doing that drawing and then use super glue while i never look back but i hear the old man and sense him waiting and saying some gibberish..my buddy is listening while i am instigating because i did not forget what he did last night..then we get in the house and instantly i realize he is getting needles so i knock him out and he had this tube of pills and i dont know why i put them all in my mouth and my friend said he wanted to stay just because he loves adderal so much..but i had just put them in my mouth and was spitting them out saying..no bro were leaving and he was kind of upset i had put them in my mouth...i remember feeling a bit buzzed as if i was light in my body(i know that is not what adderal does but this was the dream) and i ran out of the house and my buddy turned into my mother and we were holding 2 or 3 dogs..1 significant dog which is one that passed away a few years back other two i didnt know..and we started running in a north direction to a park ...now i remember it was snowy and i saw in the far distance the man coming with the wife..just walking..we enter the woods that resembles woods i used to grew up near..but there was a small cliff down about 30 feet that was never there before..we go down with the dogs and then i tell my mother to go along...i hide in the brush to the right while the man and woman come pursuing us..they dont see me..i have a 2x4 and boom whack him on his head and her..kill them and its over..

i am extremely sorry for long post and if you read it all i appreciate your effort but what the heck does this dream mean and has anyone else ever had episode dreams where they dream a similar setting but have knowledge from a past dream which changes up things..makes them more aware?

This happens to me all the time. Rarely now and days the memories of my past dreams will effect the dream I'm having in a large way. Usually there will be small signs. Like I had a dream in this one neighborhood. In that dream I had gotten killed by a evil girl that came from a comic book. A really long time later I had another dream that took place in the same neighborhood just three houses down and across the street from the house that the first dream took place in. In that dream I stopped and looked over at that house and could see the little girl standing by the window and I said to myself "never again." then the dream went on normally. Stuff like that happens a lot with me. Had three different dreams that all took place in the same dream school just on different floor.
When I was young I had a series of dreams that all where on the same alien planet. Each dream left off where the last dream ended. Whenever I have a dream that includes Walmart it's always the same over-sized Walmart with a playground at the front. I also have recurring dream friends, the ones how you don't know in real life.
I thing of all this as my personal dream world. Like if I mapped out all my dream locations that would make my dream world and that's why they tend to be connected.
