If you really wonder what Aquinas thinks about the apparitions, go to the relevant part of the Summa. He deals with the question directly. If you like, I'll get you the URL.
I did not answer the question because I haven't decided if physical and spiritual exhaust the possibilities. If you've actually read what I wrote in this thread you know I won't say physical. My gut (but acquired) reflex is to say, “Real!”
Certainly spiritual would be way closer than physical, so if I had to choose between the two I'd go with spiritual, and I'd clarify that substance is not perceived by the senses AND that the spiritual is Real, but the physical not so much.
That are the only choices.. If it is physical it would bleed...spirits do not have fled and blood..
We see these types of claims from Catholics.
Yet they NEVER seem to be able to put their fingers on just WHICH 'false' things they are speaking about.
