Probably just gas, Dingbat!

In the video Pelosi says, “He’s (Bush) saying something to the effect of we’re so glad to welcome you here, congratulations and I know you’ll probably have some different things to say about what is going on–which is correct. But, as he was saying this, he was fading and this other thing was happening to me.”
“My chair was getting crowded in,” said Pelosi. “I swear this happened, never happened before, it never happened since.”
“My chair was getting crowded in and I couldn’t figure out what it was, it was like this,” she said.
“And then I realized Susan B. Anthony, Elizabeth Cady Stanton, Lucretia Mott, Alice Paul, Sojourner Truth, you name it, they were all in that chair, they were,” said Pelosi. “More than I named and I could hear them say: ‘At last we have a seat at the table.’ And then they were gone.”
