I had such an odd and terrible nightmare last night. I still cry about it when I think about it. I would really appreciate people's opinions and take on it. anyway.. here it goes.

I was walking around in an unknown area in the country and I found this poor horse.. it was black and dirty and starving. I love animals and want to rescue them for a living so I took the horse home with me. I brought it into my house and into our tiny bathroom to wash it up. I was trying to brush it's mane and it's hair started falling out. Apparently I thought that using a different brush would help the hair not fall out so I walked out of the bathroom, closing the door behind me with the horse still inside and walked through the living room and kitchen to the laundry room to get a pet brush out of a shelf. I kept dropping and picking up the clump of horse hair I had in my hand. Then I walked back to the bathroom and opened the door and this is where it turns into a nightmare. The horse was gone but instead my mom was laying on the floor with a towel on top of her... there was blood everywhere and she was moaning and kind of rolling around in pain. I screamed and asked what happened and she said in a voice so low and weak I could barely hear her and she was crying that she went to go to the bathroom and didn't know the horse was in there.. and it became frightened and ran out, trampling her. and she said she wasn't going to make it. I of course, was sobbing and just couldn't believe what was going on. I felt guilty because i was the one who put the horse in there and left him alone. i just couldn't believe she wouldn't be there anymore. I woke up crying. It REALLY has me upset. i've been very emotional all day, of course I'm also pregnant so I guess being emotional is normal.. anyway. PLEASE help me think this dream out and give any explanations you can think of or just your opinions.. anything.. please
