I believe, as Zahir said, the writers were already toying with the idea of introducing supernatural elements to the show, thus the Josette sighting. However, it really took hold with the Phoenix storyline, which came shortly after. When that went over well, it was decided to bring in a vampire. Again, to agree with Zahir, it became a rather sloppy, incongruous mess when it became clear that Barnabas Collins was too popular to kill off as had been originally planned. So, there we went, off to 1795, which is why, despite what Barnabas had said earlier about Josette Collins and why she took a flying leap off Widow's Hill, the whole story changed dramatically. Still, as a kid, I happily went along with everything as it unfolded, and still today, here we are -- rabid fans.
