Speaking on E!'s Chelsea Lately, Love Hewitt admitted that the experience seems to be preying on her mind.
"I actually had a nightmare the other night that people were trying to deflate my boobs while I was working. They had tubes and I was trying to work, but they kept getting smaller," she told host Chelsea Handler.
"I was like, 'Guys, don't take them away!' I'm getting issues about it, I think."
The actress went on to say she still does not know who was behind the advert decision, commenting: "Some random person decided they were supposed to be smaller. I still don't know who that person is."
She added: ''Right now I'm rubbing guys for a living, so I'm fine. I have my own Fifty Shades of Grey happening every day, so I'm good.''
