Chrisitian dream about spiders and tarantula?

had a dream about a spider. Was cleaning out office or room. Man I knew asked to help me, but kept saying I had it covered. (me and my son was there) Saw a web and killed the first spider. Then saw a tarantula in the room I was sweeping out. But i hit the tarantula to kill it, but it was half dead. And then I told man to step on the tarantula and kill it, he wouldn't because he said it is harmless you took all the poison venom out of it. So he put his hand to it and it bit him, but he said he felt the venom but it wasn't enough to do any harm to him and so he played with it and said it was a boy spider and all. Can anyone tell me what they think of this. I know that all interpretation is from God and that He speaks to us in our dreams and visions. Thanking God and you in advance
