Welcome Marie. I think a call to an exterminator is probably in order.
Depends on what kind of spider that is hanging out in your bedroom.
Then there is the fact that people on drugs swear spiders or ants are crawling all over them. They the poor soles have scratches all over their face, arms and legs as the itching becomes intolerable.----Sort of like Chiggers that lay their lava under the skin to hatch.
I have no idea where you are Marie, but spiders from what I understand spend their time eating insects and hiding in dark corners, or around a water source.
My advise is to get mosquito netting, hang it over the bed and if you awaken to a colony of spiders, jumping up and down on your body, grab your cell phone and take pictures then forward them to the CDC -----
