I had a dream...but it seemed much more like a memory. The dream was so long and serious that even when i woke up i ran to search for the things i have done in my "Dream". To my surprise i actually found some things i have done in my "dream" and have NOT done while I was awake. I am really confused over this as I do not know if it was a dream or a memory. But some things i Can not remember no matter how hard i try.

It's probably a dream with strong basis in your real memories. I've had dreams like that before, though I have found that after waking up I realize that they are dreams.

I have had things like this happen to me. How it happens with me is that I sleep walk and do things but my eyes are open and I understand exactly what is happening but cant control what I do. Luckily this doesn't happen too often, or at least for me, since I just do the stupidest shit imaginable while I am like that.
For example I have walked out of my room and started to talk to myself, for some reason I took someones shoes from the closet and put them under my bed and started searching for something that I had lost in my dream in our house.
I doubt your situation may be the same thing but it might not be.

In dreams there are reality and in reality there are dreams. It happens a lot and honestly it's fun @ the same time confusing when you experienced it.
