The Church in the Ocean

I am climbing down a rock face made up of large boulders. As I am scooting and climbing down I can see my feet, they are sandled (ancient style sandles, what you may imagine people in bible times wearing.) As I get near the bottom of the rock face I can see that all that lies ahead is the sea/ocean. I am now standing on the last boulder at the bottom that separates me from the water. I look out across this vast sea and I get two pieces of information given to me. The first, is that members of the church I went to at the time are standing all throughout this sea, near and far (the whole church, though I can make out no particular person). The second is that there is no change in the depth of the water, even as far back as the eye can see. It is all specifically knee-high water. Then I see April (a good friend of my Mum, and socially an important member of the church at the time) standing in the water near the boulder I am on. She is looking up at me and stretches out her hand to me (as if to help me into the water) I reach down with my hand, and just as our hands are about to connect, a giant boulder, falls from the sky, directly above April, and smashes down on her. She somehow manages to dodge this. The boulder disappears, and unphased, she reaches up to me again to help me down. Just as our hands are about to connect again, a second boulder, (smaller than the previous one, but still large) falls down from above, directly over her, and smashes down on her and then I wake up. (Please note: I cannot remember if April was able to dodge this second boulder or if it crushed her. I just remember waking up after seeing the second boulder fall down).
