Depressing Dream

It started out as a zombie dream but then ended up changing.. The people in this changed dream kept.. shifting.. Like one minute I knew they were one person but then that same person became someone else..Anyway.. A group of us went into the mountains I don't remember the whole trip but one woman fell into a gaping hole and before she fell I pulled her up.. I remember getting strange vibes off someone.. or everyone.. I'm not sure.. in the group.. then we were in a cabin and going to play cards, but another part of the group were on some smooth flat rocks to camp.. I was with them momentarily, but someone was missing and I looked off with a heavy heart only to accept the hand that a person reached out to me to share they're spot on the ground.. In the cabin I got mad before the game started, because they were ranting about rules and what not. I ended up throwing my deck into the air and letting it fall onto the people before storming out though I did end up going back for my shoes cause it was sunny out and I didn't wanna burn my feet. I specifically remember Lon being there. He left after me, but to the campground area. I knew he was going to find his woman cheating on him and somehow got the feeling that I was going to find the same thing with Pete. I'm not with him anymore, but apparently in my dream I was. Sure enough as I got down to the house as I passed our bedroom window he was screwing another woman.. I beat the door and said I was gonna kill her and my dad was standing behind me along with my little sister. I told her to go around to the windows because even though I couldn't see through the door I could.. see what was going on in the room. Dream knowing is awesome.. Anywho.. I did end up getting in and they were hidden behind/beneath the bed which was angled upward in some odd position.. He didn't say anything but she did. She said they were gonna die in a month and something about me not understanding.. At this point I completely shut down emotionally. I'm not sure what happened in the moments between, but I guess cops were there for some reason and one ended up dead. They freaked out and we all ended up back in the rocks with him laying down and us sitting over him. Getting a bit of feeling back I try to comfort him but then she ended up caressing his face so again I shut down and get up to leave. Almost back to the cabin I fell down sobbing, but forced myself to stand up and fight back the tears because I didn't want anyone to see me crying. I opened the cabin door twice, but shut it each time then just started wandering off. Two of the females there said it was too dark to climb up this really steep hill that was oddly rowed with grass. Not listening to them they decide to follow. I couldn't get up as far as them and actually ended up sliding back down. Part of me hoped I would just slide right off the mountains edge. Instead I stopped at Lon's feet who just got back himself. I already knew he had found his girl cheating as well. Those around us finally started to get suspicious about how we were feeling so I grabbed his arm and the dream twisted with my thoughts so we were walking along a stone path in a garden like area. He started talking, saying everything was gonna be okay and what not.. The normal things he says.. which.. only he would know and I'm not repeating any of it to anyone so yeah.. After waking up I remember.. I think there were four but there might have been five.. well.. I don't know what they were.. but each represented a person/choice of something or other.. I woke up very sad..
