This bit is probably irrelevant but I'll add it just in case:
Yesterday I was out for a walk in a forest park with my friend, my brother and my two dogs. We came across a man out for a run and were talking to him for a few minutes, he was just commenting on the dogs' good condition, and general conversation. Then he sat down and we ended up talking to him for about an hour. The conversation was quite deep, about Christian morals, etc, he kept going back to this topic. We eventually had to go as my parents were waiting back at the car, but the conversation was very interesting. I got a feeling that we met him for a reason, not sure whether it was good or bad. I believe that dogs are a great indication of a good or bad person, my dogs initially liked him, but as we talked more to him, the dogs became worked up and acted aggressively towards others for the rest of the day, not something they would normally do.

Then last night I had a strange dream, I was with my friends in town, and a girl who I haven't spoken to/seen in at least a year turned up with a little black box. Inside it were 'gears' which seemed to be the currency, and a little black character (female). This character then died/was killed, and a friend tried to close the box, but the lid didn't line up properly, so the box was passed around the group until someone managed to close it. As soon as it was closed my friend and I experienced a feeling as if the world was fast-forwarding and rewinding, all at the same time, but we were unsure if others in the group experienced it. There were colours, blues and pinks and whites, all blending into one another, quite a relaxing scene, but there were numbers flying about, particularly the number 12. Myself and the other girl who had experienced this then decided we would continue shopping on our own. We were walking through a shop, and all of a sudden, she turned to me and told me that her left felt like it was becoming her right. I grabbed her and everything, including us, spun around, at least two and a half times, anti-clockwise, before ending. I didn't wake up, but my memory ends here.

Does anybody have any idea what this means, as it's really scaring me and feels important, as if I need to know. I turned 16 a few days ago and am doing GCSEs at the moment, although I'm not particularly stressed about them, but just in case that would be important. I will answer any other relevant questions too. Thanks.
