Doctor Who: The Sleep Of Reason

The near future: a man in a psychiatric hospital claims to be an alien time-traveller called "the Doctor". He once adventured across countless galaxies, fighting evil.

The past: an asylum struggles to change Victorian attitudes to the mentally ill. It catches fire in mysterious circumstances.

Something, revelling in madness, is growing ever stronger. The mysterious Dr Smith is fascinated by Laska's waking dreams and prophetic nightmares.
