Is it normal to have a dream like this?

I always have mixed dreams. First I dreamt that I had twins (I have a 6 month old in reality). So, I was in the room with my 6 m/o, newborn twins, my husband and next to us were 3 human sized stuffed Easter bunnies forming a circle. They were alive, & were supposedly there to help us care for the babies. Then I dreamt that I was being driven in a wheelchair (I can walk in reality) by a stranger into a neighborhood filled with hundreds of half dead hares. The hares literally covered the neighborhood sidewalk & road. The stranger pushing my wheelchair walked through the block as if the hares weren't there, I couldn't tell whether most of them were asleep or dead but I could hear their bones cracking & some yelping as I was being pushed in the wheelchair. At the end of the sidewalk, I saw an iguana eating a snake. There were a couple more snakes scurrying to hide. Later in my dream, I dreamt that I killed several people including an old godmother of mine, in the dream she lived inside a church. (I'm not religious at all, I was when I was a child) I always have dreams of death or something similar. Is this normal & what may these dreams mean?
