What does this dream mean?

I fell from a high cliff and thought, this is it I'm going to die. But it was the most gentle even pleasant fall you can imagine. I fell into water and it was a gentle wonderful fall, like falling on a bed of fluffy cotton. When I was in the water I turned and saw a shark, I thought this is it. I'm going to die but I will swim hard and try to reach the shore. I turned to see how close the shark was to me and he was just sitting looking at me and didn't come for me. Then I saw a bunch of snakes and I thought this is it. I begin to swim fast again the looked and they were just looking at me and did not come my way. Then I saw an alligator and he did not come for me. Finally I reached the shore safely. I dreamed this three times.
