I cannot understand what you are saying, and because of that, I really don't know what episode has Bart waking up, Lisa wearing her pajamas and with sleeping blind masks.

If you're talking about Bart disguising as Lisa (i.e. wearing Lisa's pjs and styling his hair as Lisa's), then it's from "Gone Maggie Gone".
