What do these dreams mean?

I have had a few dreams over the past few months which disturbed me.

(1) I dreamed that I kept seeing this guy who I used to love (but he rejected me) in different places, but he was always ignoring me and pretended we didn't even know each other. Suddenly I was high above the earth and looked down and saw him and only two other people in a huge 747 plane that was hurtling towards the ground about to crash. I could see the plane without the roof, like I had x-ray vision and he had on a fluorescent yellow t-shirt and was not at all stressed about the situation.

(2) I have dreamed about dead animals being in my house and I was so freaked out to find the animals and didn't know what to do. The first time it was a whole heap of dead dogs (absolutely awful dream!!). Last week it was a dead wombat (http://en.wikipedia.org/wiki/Wombat). I was really disturbed. I don't own any pets at all.

(3) Last night I had a dream where I went to visit my family and they were back living in my childhood home, which we haven't lived in since 1993 . When I went inside the house was completely different. My dad had tried to remodel it, but had done an awful job and there were bare brick walls with mortar, just left there unfinished. Many rooms were not where they used to be, like the kitchen was in a different place and so were the bedrooms etc. I went into the backyard where we used to have a swimming pool. At first I couldn't see it, but when I walked further into the backyard, I saw that it was not only still there, but the swimming pool was now brown and led out into a raging river and then into a large expanse of water that the backyard opened out into. I then saw a person I know, but I don't know her that well in real life and she was beside the pool crying. I met her in a different country only several times and she has never even been to my house and in the dream when she saw me she said it's good to see that someone is as upset as her. Even though I wasn't crying.

Things that are going on in my life - if this will help the interpretation ----

I've just come back to my home country after living overseas for four years.
I've recently finished treatment for anorexia and bulimia, which I had for ten years and despite many attempts to get better, this is the first time I have felt I am in recovery.
I was rejected by this guy that I loved.

(4) I dreamed that I was at a party and there were two women holding dead babies (awful!!). Everyone was mourning for the women with their dead babies. Suddenly one of the mothers touched her dead baby's eyes and the baby came back from the dead and everyone was really happy.
