The spell dimension door reads (PHB, p. 221):
If you arrive in in a place that is already occupied by a solid body, you and each creature travelling with you take 1d6 points of damage and are shunted to a random open place within 100 feet of the intended location.
- Does "a solid body" include creatures?
- If no, what happens if you suddenly share space with another creature?
- What happens to the other travelers if only they and not the caster land in an occupied space?
