She is saying, she is a soul who in a past time was in a reptilian body.

I've entertained the theory this planet has been used in a manner similar to how Great Britain "seeded" Australia with their trouble makers. This may be done my many different advanced (or any type really) of culture who wanted not to kill a being but unload for a period of time. This is not a soul trap like many here believe they believe. There is no such thing but it may indeed be a great distraction.
