The 16-year-old had claimed he was sleepwalking and was "on a mission" to protect himself from a zombie apocalypse when he carried out his attack.
Jurors at Exeter Crown Court found him guilty of attempted murder after he admitted to assaulting the two boys and the housemaster at Blundell's School in Tiverton.
The court heard that the teenager, who cannot be identified for legal reasons, had waited for the two boys to be asleep in their cabin-style beds before attacking them shortly before 1am on 9 June last year.
Housemaster Henry Roffe-Silvester was awoken by the noises coming from the boarding house and went to investigate, at which point he saw a silhouetted figure standing in the bedroom.
The schoolboy turned towards him and repeatedly struck him over the head with a hammer, before he managed to flee and dial 999, believing there was an intruder.
