Hello there all.

I just thought I'd share something mildly interesting with you, and was wondering if anyone has had similar experiences, or any insights etc.
I have been performing evocations for a few years now, however I'd only ever done them inside, or if outside then in a private place (ie garden).
A couple of months back I was up in Loch Ness, Scotland doing a spot of Nessie hunting (no really!) and one of my other things to do was some evocation work, namely evocating Amon (a spirit I have used successfully before).
Anyway the spot I chose was in the forest near to the Loch, in a small clearing off of a footpath. The area was remote even by north highlands standards. However even while I was setting up and waiting for the start time of the ritual a couple of dogwalkers went past now and then, very friendly, hello etc, there dogs ran up for me to pet etc.
To get to the point, as i was performing the ritual, I paused just before the first conjuration. To my horror I heard and saw a man coming down the path with his dog. I braced myself ready for some awkward questions. But to my surprise he just walked past AS IF I DIDNT EXIST. Even his dog didnt look at me.
I cannot believe under normal circumstances he could miss me, it was daylight, i was in an open space with no trees blocking me from the path, there were candles, billowing incence smoke, i was oddly dressed pointing a dagger and bellowing divine names loudly. Of course I know stories of others being invisisble when in a circle, but ive never experienced this myself.
The other strange thing, after id packed up i went to leave but had a feeling as if i had to stay. it was a nice friendly feeling, i cant describe it except it was similar to leaving a group of friends you know you wont see for a while. as if the place didnt want me to go. it was really hard to turn and leave. im a great beleiver in the fair folk and have spent many times in country places meditiating etc trying to get a 'sacred spot' but never to any avail. so how i got that feeling there i dont know. i didnt offer them anything, or even acknowledge them, all i did was sit there for a few hours reading and playing my tin whistle then evoked a spirit.
I have my own theories on these things, but i was wondering if anyone had some too, or similar experiences?
