Dream About A Snake Bite In My Bedroom

I'm in my irl bedroom and the light was off and I like turn it on to see a big snake on my floor and then I try to keep the light on to see it and it launches itself at me and I try to get out the bed so I don't get bit but I get bite anyway. There was a only one bite on my leg and not two bites where the two fangs are supposed to latch on, but there was one bite. The swelling wasn't bad but I think I was reacting to it, like my body was reacting to it. I then got the snake inside my room and close the door. And then I went to my mother and I showed her the bite and she said that we should call the hospital, and so then we did and then I told her that so we did and the doctor on the phone said to look for any symptoms in the next 5 days. After they hung up, I opened the door and there was a huge red bulging blister on my right leg where the bite was at my right foot and it was scary, something I never witnessed before. I didn't see the snake in my room but the pest control team was all in my room and they were spraying everywhere. That's the end of my dream I suppose.
