Playing with a Ouija board is often associated with contacting the dead and so when it starts talking to you it can be quite a shock and very scary, causing people to feel like they are having a heart attack
Context: The other night me and my friend played with a Ouija board... and it spoke to us.
Hypothesis: We were playing with a Ouija board and all of a sudden it started talking to us, which made me feel like I was having a heart attack.

Is the hypothesis incorrect? (Yes, no, or unknown)?
