For me, the difference between LD and AP is not just qualitative or energetic, but also relies on where it is sourced.

For me, dreaming and lucid dreaming are primarily 'internally informed' - that is, their contents come from within my own mind. OBE and AP, on the other hand, I call 'externally informed', the experiences and information seeming to come from primarily outside my own person and mind.

Really though there are no hard and fast rules - one can contain elements of the other or move from one into the other - though the definitions help me to sort the experiences.

I suppose I'm just not that disciplined.
