Dr Hurlburt says that there are great variations in the way our inner lives play themselves out in our heads. ‘My research says that there are a lot of people who don’t ever naturally form images, and then there are other people who form very florid, high-fidelity, Technicolor, moving images.’ Some people have inner lives dominated by speech, body sensations or emotions, and yet others by ‘unsymbolized thinking’ that can take the form of wordless questions like, ‘Should I have the ham sandwich or the roast beef?’
