When she wakes the only thing she knows is terror and revulsion. Someone is in the room with her. Worse, they're touching her. She screams and flails her limbs wildly trying to get away, or get them to go away.
(Her mom who had come to get her up for school tries to calm her but it only makes it worse)
After what seems like forever (but is really only about thirty seconds) she's alone in the room. She manages to get up to slam the door shut. The blind panic fades a little but she is still terrified. Someone could come back in at any minute. Her parents are in the house. Her brothers have moved out but they drop by regularly. Also there's cars going by outside and most of those (except the automated delivery vans) have people in them. She wants to get her swimming earplugs but then she might not hear someone trying to come back into the room so that's unacceptable.
Her mother is outside the door again, speaking to her. This time she's able to recognize the voice but the words are a blur. She can only scream at her to go away.
