TC - No you're not nutty - I do believe there are many things which happen and there is no explanation for them.
I remember reading a book some months ago re: angels and if you see a white feather floating to earth with no reason as to why it is there - eg. no birds around - it is an angel passing.
Since reading this I have on the odd occasion noticed floating white feathers - and the thought that it's a passing angel is thrilling.
I also believe that often people who have passed over do try and communicate with loved ones left behind. In times of stress I notice I 'talk' to my late Mum and Dad. It often helps.
