Yes, there are completely two different things being referred to regarding OBE's and LD's.

OBE's refer to a metaphysical, astral, or spiritual entity physically moving about which occurs during a deep metitation or sleep.

Lucid Dreams are defined simply as being aware that you're dreaming. That's it, no spiritual or metaphysical strings attached (no pun intended).

The confusion sometimes lies in that some believe that the experience of an OBE is really a lucid dream about leaving the body. Likewise, those OBE die-hard fans can say that lucid dreaming is the person believing they are dreaming when in fact they are leaving their body and passing through different dimensions, universes, etc.

Interpretation is up to the individual of which is fact, however, the definitions themselves of what an OBE and LD are remain clear - two different things.
