I have had a few dreams similar to the one I am about to say...

I was sleeping, and I dreampt about my mom walking the dog down the road. The dream was very realistic, and it was though I was there, but just watching the event take place. She was walking down the road, and I was wondering if I could alter this dream like I do my other dreams. I tried a simple experiment that was easy to do in other dreams, I concentrated on the wind blowing in a gust, and it happened. The trees and leaves violently blew, and the dog (a jack russel terrier) jerked the leash out of my mom's hand and ran toward my direction while barking. Using my dream controlling skills, I made him walk back to my mom. The leash that she was using was the red leash, which she does not normally use because it was shorter.
When I woke up, I heard the door shut and found out that my mom just got back from walking the dog. I went out and greeted her, and the dog started barking at me, which was wierd, but she just stuck him in his kennel. Then she told me that the dog almost escaped, and then I stopped her, and asked her what leash she used, because I was thinking "no way". She responded that she used the red leash because she could not find the other one. This was another shock to me. Then she started to tell me the story of how the gust of wind came, and the dog was running and barking and then stopped and went back to her, which he never does because he wants to just run around. By the time she finished, my mouth was hanging open and I was both shocked and in disbelief.
I did not tell her what I had experienced, because she is not one to believe in that sort of thing, I just said that we were lucky that he did not run away.

Please tell me what this could be because I have no idea. I have been afraid to tell anyone because they would just think that I was crazy or making something up. Please help me.
