Hi, this is a False Black Widow, Steatoda grossa. Although it’s a common spider found in homes it’s not something you’d typically find in a bed so it got there by accident. If you see more you can reduce the number of spiders you find in your home by sealing off cracks around floors, doors, windows, foundation, etc., vacuum everywhere and empty the canister outside.

Does it look pink and white because of the photo’s overexposure or can these be S.grossa’s natural colors?

Purplish-brown and cream … I’ve seen a lot of submissions with that coloration, mostly natural. https://bugguide.net/node/view/1360882/bgimage
