ABANDONED. Sci-Fi book about a house that experience a time/dimensional shift where the home is then occupied by grey shapeless blob like creatures

[Samantha]

I read this book a few years back. The book is about a house that has a history of it inhabitants going missing. The new owners experience a "time ripple" or dimensional shift while in the house, which happens every set amount of years, and the current individual get taken to a time/dimension when the house is now in disrepair, and its home to creatures that look like shapeless gray blobs. They characters come up with a theory that the grey blobs are actually the past owes you have been stuck in this time/dimension shift before, and if they can't figure out how to get back that they will also become grey blobs.
