I don't mean to play at being Edgar Cayce here, in fact I don't think I'm about to say anything particularly profound even, but this type of recurring dream kinda strikes me as a perception on your part of some underlying vulnerability like a neglected health issue maybe, or a new relationship entered into by a relative that leaves you mildly uneasy, etc. I don't think dreams are premonitions so much as signposts, indicating some overlooked detail or the like. So, like it might be time to do a scan, as it were, re home security, health, the status of people close to you etc. I hope this doesn't sound like Ann Landers. But I do think dreams are quite significant, especially the recurring ones. And not because I think they're messages from another dimension or the like (although who knows?), but more like a persistent (even nagging) reminder to take stock.
