The original series reported dream content correlating with a sender's target image above chance, but no other laboratory reproduced the effect, and the series itself was never repeated at a comparable scale. Irvin Child argued in 1985 that the result was dismissed rather than evaluated, which is a claim about how the field responded rather than a claim that anyone has since run the missing replication.
What would resolve this A preregistered, multi-night sleep laboratory replication with automated target selection, blind judging of dream transcripts against a randomized image pool, and a sample size and analysis plan fixed in advance.
