"A water sign, Scorpios often are obsessive about their relationships and spend a great deal of time strategizing how to get the things (and people) that they want. Because of this, Scorpios can spend long hours into the night watching the shadows on their walls, sometimes afraid to dream due to fear of nightmares." Of all the signs, this one is the least likely to be a morning person.
