Does a creature constitute a solid body with respect to Dimension Door?

Question

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.

1. Does "a solid body" include creatures?
2. If no, what happens if you suddenly share space with another creature?
3. What happens to the other travelers if only they and not the caster land in an occupied space?

Answer 1

Yes: a creature is a solid body

1. A creature would fit the dictionary definition of solid body. In context, the spell's wording appears intended to account for mediums (liquids, gasses, etc) that one could normally occupy. Later versions of the Dimension Door rules are more explicit.
2. N/A
3. Although this is a DM call, the spell says "All creatures to be transported must be in contact with one another", so one could surmise that they should arrive that way (even if that means that the whole group gets shunted to the nearest free space).
