SUFFUSION: the act of spreading throughout or over
"The suffusion of the brain will increase quickly, so we must trephine at once or it may be too late." (p.292, Seward's Diary)
Renfield talks about a dream he had about Dracula where he bits Mina. The men all run to Mina and Jonathan's room and find Dracula forcing Mina to drink his blood. They chase him off and recover Mina and Jonathan. Arthur and Quincey find that all the manuscripts have been burned and Renfield is dead in his room. Dracula says he now has mind power over Mina.
