hello grace and welcome to the forums here.
This is a great place to discuss questions like the one you posted, and get other people's opinions as to what it may mean, and help you explore it in terms of what it means for you.
But you should never be afraid to ask your T what he means by something,
especially when he throws out a technical term like that one. A lot of times it catches us off guard but it might make a good topic for you to bring up at your next session.
You'll find a lot of support and understanding here and I hope you like being a member of this community.
(Notice that I posted 4 paragraphs and I didn't even answer your question

-- that's me, someday they are going to boot me out of here
