Hi Lilas,
That sounds really interesting and I agree with Marydean that it sounds like it could be some spiritual force/link. I noticed your post because I am currently reading a very interesting book by Allison DuBois called "we are their heaven-why the dead never leave us". I have found it to be a very fulfilling and thought-provoking read. It describes how spirits can influence our lives in these types of ways. Do you have any loved ones who might be trying to reassure you that they are there with you? Maybe it is something that will come to you later on? I think whatever it is, it is a good sign/force. HTH.
