I Saw you in the mirror

About 10 minutes after we had left the campsite this morning driving along a twisty country road following Lake Windermere, I thought I saw the flash of someone's headlights in my mirror as if they were flashing me. I looked in the mirror and couldn't see anyone because the road was so twisty and undulating. A couple of seconds later I felt Zach's presence, it overwhelmed me as it so strong. I looked in my mirror again and I caught a glimpse of a silver car behind me in the distance, after I drove around the next corner and glanced in my mirror again it was Zach's BMW M3 right behind me, his model is so rare now and I could feel it was him. The next thought that came into my head was " Oh Zach's behind me" not shock, surprise, disbelief or anything like that, it felt completely normal, it was as if our two realities had blended. I drove for may be a minute feeling, knowing he was behind and it felt completely normal, I caught another glimpse or two of his car as I turned around a corner or two and then the feeling left as quickly as it arrived. I looked behind again knowing he wouldn't be there and the road behind me was clear. There had been no turn offs during that time, it was him. Strangely through the experience which lasted about 1 1/2 minutes I didn't say anything to Krista and I don't know why, it was like I too was in two worlds. After it ended I thought I must have imagined it, and again I don't know why I'd think that. A few minutes later we came to the end of the road and Krista said " that would be a great road to take the Alfa down, it would be nice to drive it on these roads but we'd never leave the dogs behind". I though to myself Krista must have also been connected to Zach at the same time for her to say such a thing out of the blue. Then as we sat at the road junction a new BMW M2 and M3 came past us together immediately followed by 3 Land Rover Defenders in convoy. We both said well that a sign from Zach because he always does things in 3's and to see and M2 and an M3 together with 3 defenders is no coincidence.
