I once had two dreams in which I felt a distinct admonition to the effect of, “If you don’t do more with your life now and stop wasting time, you’re going to regret it later on when you’re older and much time has passed.”
To call those two dreams of mine “life changing” might be a bit of an exaggeration, but have you ever had your life significantly affected or changed by a dream?
It wasn’t just one dream but a series of dreams over a short period of time. Had just gone through divorce and was at the bottom emotionally. My dreams were a combination of exaggerated metaphorical, symbolic examples of what I had become and what I could be. I started acting on them and life got better and stayed better.
Not very profound, but I once had a dream where I could juggle. I had never juggled before in my life. The next day, I picked up three pool balls and started juggling. It felt very natural; the muscle memory was just… there, like it was something I’d always done. Weird.
Did it change my life? Well, now I can juggle. 
Not life-changing in any big way for me - they can be a useful emotional barometer, though.
Like the way you can be vaguely feeling down, or stressed out, but having someone actually say ‘Man you look stressed, what’s wrong’ totally brings it into focus? If I have a classic worry dream [running a race where the course and event unravels, or trying desperately to catch a plane at an airport that turns into a labyrinth], it’s a similar feeling - good way of taking stock that something’s not going well and needs to be dealt with.
I once got warnings in a dream that I didn’t understand or listen to, but I wish I had.
Not me, but apparently, Seattle quarterback Russell Wilson is as religious as he is because he dreamed he met Jesus when he was a kid.
I dream regularly, like anyone else, but I don’t remember my dreams. Dreams are funny though. For example, I used to get really annoyed when I went through a deja-vu experience and couldn’t figure out where I had seen those things before. Until one day when I realized it had been an oneiric experience.
Life changing dreams are often related to inner conflicts or issues that need to be addressed. There were situations in my life when I delayed taking action and a certain dream persuaded me to tackle a situation instead of ignoring it.
One of the dreams that I’ve never been able to forget is the one I had before my mother died.
It was summer when I went to her place to see how she was doing and I noticed a weird black and white bunny painting on the wall. My mother was a writer and an artist, but I couldn’t understand why she would produce something so unpleasant. The bunnies had evil expressions and the landscape was simply grim. I asked her why I she had painted those creepy bunnies and she told me she thought they were cute. Those creatures really looked like bunnies from hell.
The night I returned to my place I dreamed that I was attending my mother’s funerals and I spotted the Grim Reaper in the crowd. It was a dark old lady dressed in black, who was staring at me. I woke up all of a sudden, drenched in sweat, but I couldn’t get rid of the Grim Reaper’s image. I could have turned the lights on but I didn’t want to disturb my family. When I closed my eyes, the dream resumed. When I opened them, I could clearly see the Grim Reaper’s face in my bookcase glass door. Of course I knew there was nothing there (I’m not a religious person), but it felt really uncomfortable.
My mother died the next January and I hate that I couldn’t prevent her untimely death.
I’ve had nightmares that shook me up, pretty bad. I’ve even had a few good dreams that shook me up, too.
And, maybe not life-changing, but I’ve had a few creative ideas—story concepts, plots, bits of dialogue—that came to me in dreams. Including a melody and a scrap of a song, once—and I’ve never written a song or played an instrument in my life.
I recent;y had a dream, I was driving in my car. For some reason, I was looking for my very first elementary school. In the dream, I remember my mom telling me it was on “such n such” street.
When I woke up that morning, curiosity got the better of me so I Googled my old school. And sure enough, said school was on such n such street. Just like in the dream.
I thought that was amazing! No way in hell I could recall that on my own. Hell, I can’t even recall it right now! LOL.
Okay, not life changing. Still though…
I have had recurring dreams about flying nearly my entire life. Most are very different approaches to flying but the one thing they all have in common are the physical feelings I would get if I were flying, at supersonic speeds the air is so shrill it is literally screaming and burning my skin. My body will always transform itself in the dreams to best accommodate the type of flying I am doing.
Not really a dream. I have a house that is in the path of a road project. They made an offer that was not what I thought it should be. I initially declined the offer. One night I woke up at about 3 am and was instantly super wide awake and thinking about the whole situation. Suddenly I could see a very clear path of how my attempts to negotiate a better price could easily end with me getting even less. There was almost literally a voice in my head saying “Take the money, dumbass!” It suddenly seemed so clear that I should do exactly that and so I did. I think it was my subconscious mind suddenly asserting control.
