While reading Chapter 5, I came across the term "sleep paralysis", in which the person is unable to move after just falling asleep or have just woken up. I have never heard of this term prior to reading this text book, but I knew exactly what it was describing.
Like examples in the book, different cultures have different explanations for this experience. In the Hmong culture, we call it "dab tsog", literally translating to "crushing ghost/demon." Sometimes the people sleeping even see the "ghost/demon" sitting on their chests. Because I had previously believed that sleep paralysis was caused to ghosts, I questioned the books explanations of why and how the phenomenon occurs. Did psychologist, scientists, or health care professionals run tests on individuals and abruptly wake them up? Did they hook machines up to individuals to test their anxiety levels? Because the book did not give such information, all of these questions ran through my head and I found myself being placed in the category of belief perseverance.
It's not that I don't believe in sleep paralysis, or agree with why/how it happens; it's just that I was previously believed it to be caused by something else. What do you believe? Is there an explanation of this phenomenon in your culture or country?
