Seeing an angel! So beautiful
When a spirit passes, sometimes odd events can occur, because of the release of energy which also occurs. That was probably the cold sensation you felt. A few years ago, a number of relatives died in my family, and on occasions, their passing was followed by strange events; nothing major or serious, just noticeable.
My Dad passed away six years ago now, and shortly after, I went to Tottenham Hotspur football club shop to get a scarf to wear at the funeral. I was out of work at the time, and was wondering if spending money was a good idea, but as I approached the till, the lights flickered off, and then on again. I took that as a sign from my Dad that he was now acting as my spirit guide/helper, and that all would be well. In the long term, it was.
A year later, my grandmother passed away, and I was working the following day. I was alone in my area at work, and was doing some cleaning. Crucially, the floors were clear of any objects. For about an hour, nobody else came into the zone, yet I kept on finding dropped coins on the floor. I didn't see or hear them being dropped, and couldn't think of any way they could have got there. Having read up on this, I then found out that dropped coins on the ground are a sign from angels and passed loved ones, that they are safe, well, and looking out for you.
