Slow, fast, or jumper? Body shape, color, signs on the body? It's just a spider. I had one land on my hat once at a party. Everybody freaked out. I just shook it off. The thing is, spiders don't really like humans and stay away as best they can. The guy that landed on my hat probably though I was a piece of furniture. I have funnel web spiders that made the basement their home in this house. You never see them out and about, but you know they do leave their webs every once in a while. If yours is dark and slow, probably a normal type of harmless house spider. If it is thin and a sprinter with markings, it's probably kin to a grass spider, also harmless and skittish.
