Snake dream

I just woke up from the scariest dream! Ugh....
There was some kind of supernatural feeling about the whole dream, it was scary, I was scared and I woke up that way...scared. I hate the way dreams for me can linger, I mean whatever feelings I had in them linger.
In this dream, I had 4 poisonous snakes. I don't like snakes and would not have one but I had bought these in the dream. They were all together in the same cage, they were about 5 feet long each I guess. The cage was a problem because it was a dogs crate and the snakes kept getting out and roaming the house. There were a couple people in the house with me, thank God, because I was too scared of them to catch them, so these people caught them for me but it just kept happening because the cage was wrong. I would look at the cage and the snakes would be going around and around the cage and I knew they were gonna get out again!
One of the snakes was green...a bright green.
I heard a commotion outside the house and I went out to see what was going on. The green snake was wrapped around the upper torso of a boy who was standing up, and the head of the snake came up from behind the boys head and was trying to bite into the boys skull. there was a man behind them with his hands on the snakes head, trying to keep it from biting into the boy but he was yelling that the snake was too strong, and he needed help quick. I grapped a huge pair of wire cutters and went to them and cut part of the snake off. this caused the snake to release its grip. The snake died. But, it had managed to bite into the boys head a little. I remember looking at the boys wound and looking at his eyes and calling 911. He had surgery and then he was okay.
I have no idea what this dream means but it was a scary one. I feel better having written it out :::::whew::::

Traditionally, a snake is a phallic symbol. Phallic doesn't necessarily mean penis; it means power. So I would guess something with power seems threatening to you. Of course, green as a color is a fertility symbol. Are you a man or a woman? I am a woman, and I used to have dreams like this when I was ovulating. But perhaps you are a man, and that has no relevance. What do you think?

Also, the number of poisonous snakes---4. Did you know that there are exactly 4 kinds of snakes in the U.S. that are poisonous? And all 4 of them can be found in Oklahoma.....just sayin'
