Claustrophobia?

Ever since I've been pregnant (25 weeks), I have this weird claustrophobic feeling. It happens at different times. For instance, when my DH kisses me, I instantly feel that way. Also, if the cover is on my neck, I feel like I can't breathe. I know this is crazy, but I don't know what the deal is. Anyone else experience this?
