You are probably 50 times bigger than the spider.
NOW, let's suppose you are near an animal that is that is about 200 feet in length. How much trouble will YOU cause that animal until it becomes aware of you? Probably not very much right?
Basically, you are quite safe.
Spiders are normally more afraid of you then you are of them. That spider is gonna stay away form you as far as possible. Most of what you are afraid of is psychological fears inside your head that arent real! Just be calm. I hate spiders, but in reality, you prob wont see this lil guy again after tonight. He'll be long gone without a worry.
You don't have spider troubles, you have fear of spider troubles.
Rest assured, the spider is not going to bother you at all while sleeping.
As for your fear, you can read the following, and I hope this helps:
