Quote context

[...]

- All my life, I've had a dreadful fear of premature burial. I awaken sometimes screaming with nightmares in which I see myself buried alive, waking to find myself entombed, without air stifling, and no escape.

- I know. It's not an uncommon fear.

- Perhaps I have more reason for my fear than most.

- You see, since childhood I've been ill. I have fainting spells. Trances.

- Was it I who mentioned catalepsy yesterday?

- Yes. I couldn't tell you then.

- I've had trances lasting more than a day with almost complete suspension of heartbeat and respiration.

- I should have known. I'm terribly sorry. I would never have spoken as I did.

- But you need not fear. I will take every precaution, make every known test if you are unlucky...

- Thank you.

- Now that you understand, I'm no longer afraid.

- I suppose you want to hear my prayer to Hermes?
