There are times when I am in bed, and my kitty will attack me viciously. Why does she do this? I hand-raised her from 4 weeks old and she is affectionate, but then her eyes dilate and she attacks.

The dilated eyes suggest this is play behavior, no matter how painful for you! Hand-reared kittens lack social skills learnt from play with other kittens, and she's never learnt how to inhibit her biting or scratching during play. In the short term, if you've been injured you may need to stop her being in the bedroom. Never play games with your hands and use toys such as a wing-on-a-string that are at a distance from her. Also, if she does pounce, let her know it hurts by screeching, although avoid pulling away as this only triggers further hunting behavior.
