We are told that they can only terminate on surfaces, grain boundaries or other dislocations but we are not told why they can't terminate inside the crystal.

Citation? It's a lot easier to answer when we know the exact phrasing of the statement in question. But I suspect you'll see the reason (if I understand what you're getting at) if you arrange a bunch of marbles, simulating a 2-D crystalline structure with a dislocation.
