What are some of some symptoms of witchcraft that Abigail and her followers show in The Crucible?I need to know some symptoms of witchcraft...

In Act I, Scene i, Betty Parris and Ruth Putnam are both
unable to wake: 

ABIGAIL: Yes, Uncle. (He goes out with
Putnam.) How is Ruth sick?
MERCY: It’s weirdish, I know not—she seems to walk
like a dead one since last night.

Abigail attributes their
inability to wake to excessive fright as a result of Reverend Parris catching them
dancing in the woods around a pot with frogs in it.  They had convinced the Parris'
slave, Tituba, to help them cast a spell on Elizabeth Proctor so that John Proctor would
leave her for Abigail. 

In Act I, Scene i Betty also tries
to fly out the window and she screams when she hears people praying in the Parris
home.
