Hi, this is possibly a Cheiracanthum mildei, Long-legged Sac Spider. They are very populous in houses and many are reaching adulthood this time of year. They spend most of their time on ceilings and high on walls. I’ve been bitten by Cheiracanthum spiders outdoors, it initially feels like an ant bite. They have no interest in you or any other mammals and won’t go out of their way to interact with you. They eat other spiders and insects that fly up to the ceiling and possibly mites. So, much more beneficial than dangerous.
