Blanche says she doesn't want realism. What does she want ? What does she do to get it?

Blanche doesn't want realism, she wants magic. In order to get it, she lies..... and hides.

BLANCHE: I don't want realism. I want magic!
[Mitch laughs]
Yes, yes, magic! I try to give that to people. I misrepresent things to them. I don't tell truth, I tell what ought to be truth. And if that is sinful, then let me be damned for it!--Don't turn the light on!
