I think this was part of an anthology I read in my teens.It centres around a group of scientists in a lab observing another dimension through some form of apparatus. They see what appears to be an idyllic looking house with children? playing on a lawn. One of the scientists becomes so smitten over time that he eventually jumps through the apparatus into the other world. Whereupon the children? immediately change form and become predatory creatures and eat him, whilst his colleagues are still watching on earth.Thanks!
