Science of Inception – sedatives, dissociatives and dreaming

// August 1st, 2010 // 11 Comments » // Drugs, Science in the Movies

inception movieInception is a movie which grabs you by the throat and won’t let you go. Having seen it, I can’t stop thinking about it and I just have to write something down. For those who haven’t seen it, I will keep this vague enough to avoid spoilers.

Dreaming is, well, weird. We don’t really know why or how it happens, though we have plenty of theories. I’ve had dreams so real that afterward I think they happened in life. It makes you think, if we can dream or imagine something that looks real, how real is reality? Could it all be a chemical hallucination, reality merely a response to stimuli that triggers a release of endogenous drugs? What makes reality more real than a dream?

If you really start thinking about it, nothing seems real. So let’s not think about it right now.

Instead let’s talk about sedatives – drugs which relax the body and the mind. Examples include alcohol, kava, valium, and barbiturates which are sometimes used as general anaesthetic (we made one at Uni once – sleepiest class ever!) Sedatives can be used to treat insomnia, and come with the danger of addiction.

So sedatives can put you to sleep, but what about dreams? The few times I’ve had general anaesthetic I haven’t had any dreams at all, and I’ve never noticed different dreams after a big night of drinking rum or sharing kava on the islands.

houseI’ve been racking my brains trying to think of a drug that enhances dreams, and I think I’ve found one. Ketamine, the horse tranquiliser known on the streets as Special K. They had it once in House – the episode “No Reason” starts with House getting shot and given ketamine as anaesthetic. The rest of the episode he hallucinates wildly and finally decides everything is a dream and kills a patient to prove it – then it flashes back to the start as House is rushed to the emergency room and says “Tell Cuddy I want ketamine.” And the whole thing was a dream. Best episode EVER.

Based on that and descriptions on Erowid I think ketamine is a good contender for inducing dreams.

It can act like a sedative (you know, seeing as it’s a tranquiliser and all) but it’s actually classed as a dissociative. Being awake under a sedative means being able to react to stimulus, but with ketamine someone is in a trancelike state with analgesic (not anal gesic, sir, the pills go in your mouth) and amnesic properties.

If I know a dream is about to become a nightmare, I can usually just wake up out of it. Sweet, right? Yes, except sometimes when I wake up I try to turn on the light and the power is out. Then I know I’m still dreaming, and the nightmare starts again. I’ve woken up into other dreams ten times in a row before actually waking up. Does that happen to anyone else, or am I as mad as Ahab?

So, even after all that research and writing, I still can’t get Inception out of my head. I think I’ll have to see it again next time I’m on shore. Come with me?
