So, it starts like this.
Im with my girlfriend of 3 years and we're arguing, I got mad so I left her house and went home. I was digging through the pile of junk in my closet for no reason and a picture of my ex from like 4 years ago fell out and I had this sort of flashback(of something that never happened in real life, of course), she was sitting on a hill in this park we would hang out in. Next to her was this patch of grass that looked like someone had dug out and she turned around and started to claw at, like she was digging, then said "you know where to find me". So next in the dream I went to the park. I found the hill and started digging but I found nothing. Then I looked left and saw the strange patch of grass, began digging and there was a pink box inside. I took out the box(about the size of a suitcase) and opened it.
It was like a time capsule, pictures of her growing up, objects of importance, I thought to myself how I never remembered her mentioning this box to me.
Then this is where it got strange, this is why it felt like the longest dream I ever had.
As I was looking through the box the dream went into sort of a flashback. I watched her grow up and stuff, up until the point where she met me. I watched us, I pretty much saw our lives together if we didnt break up(from a third person view).
Then when we were like 40 and had kids and what not, we were arguing. She looked at me and said "This should have never happened. I shouldn't have changed anything. Go back to the past."
And in my dream I was back sitting on the hill. I felt sad, and depressed. Then I thought to myself if I just experienced time travel.
Next thing I know it was over. I woke up.
This dream shouldnt have felt like a nightmare, but it did. Its not like I dont think about that ex ever so my brain is trying to remind me of her. Its just strange. It felt so real. Anyone know what this means? Please help, Im at a loss.
