I've ever learned dream interpretation. Actually, you just have to think logically about the dream. The tree is a stable living thing that refers to our health. If the tree is beautiful green and flowering, the better our health. The house symbolizes the human body. Eg roof = head, brain. If a tree falls, our health will collapse. When a house collapses, it means the worst. I'm sorry I had to write this. I hope you didn't dream this. ?
