Just to confirm, you didnt feel the emotion from the dream, but the emotion formed naturally because of the dream?
Depression: My dream started with me getting up, I had a fairly normal and boring start to a day and then things started going wrong, things escalated and got worse and worse, and the weird part was just how detailed it was, i didnt skip any time that I noticed, i experienced a whole damned day that just got so bad towards the end that I killed myself, waking myself up, but because I had experienced a whole day so bad I had decided to kill myself, because I had the memories of the whole wretched day, that feeling persisted as if I had actually had the day.
Loss: This one sucked, I had a dream where I had a beautiful girlfriend, a wonderful life, I was happy and content in a way I have never felt before in my whole life, I was complete, again the feelings didnt come with the dream, but from living the dream, I was just so happy. I have only felt content once in my life (outside of my dream) and that was the first time I got over depression, for about a week I felt content. This was better than that. It felt so real and I embraced it so completely that when it just suddenly ended and I woke up, i felt heartbroken, the dream still haunts me.
Hatred: Like depression this started like a normal day, but very quickly I got into an argument with my housemate Paulo, it was an argument I had been avoiding having so the feelings were real, and he just dismissed them so callously, that I escalated, and he escalated, and by the end of a day in this dream we were both battered and badly injured from our escalating attempts to break the other and trying with our last breaths to kill each other, I remember us both lying beaten on the floor of a warehouse and I dragged myself (too hurt to stand) over to where he was lying bleeding and starting strangling him, only when the light was leaving his eyes did I wake up. That hatred was something I hadnt felt before, I WANTED to kill him, i felt it so clearly in that dream, and I saw him less than 10 minutes after I woke and that feeling hadnt faded. I just had to remind myself it was a dream and leave quickly.
These dreams were orchestrated, like they were on purpose by a conscious mind, I generally dont remember my dreams, and the ones I do fade quickly, but these never left me, never faded, they stayed like real memories, if you had dreams like this too, then I suppose the human subconscious is more cruel than I thought, because I always thought (and hoped) that these dreams were some unique fluke of a creative depressed mind wanting to self destruct.
My brother had exactly this, a forewarning of illness, he would get the same dream every time, he dreamt he was in a white room with many floating pillows which were all crinkly and he was trying to fluff them smooth, but they kept crinkling, and invariably, a day or two later he would get sick. Im not sure if he still gets the dream, but he definitely mentioned it a lot growing up.
