A group of lights in darting flight pattern (impossible to be from earth) over Yosemite, seemed to be aware of my watching.

I was at an elevation of about 10,000 feet in the NW region(I think) of the Park.  I was laying on the hood of my car gazing at the clear night sky.  I noticed a very small light that was clearly too high to be an airplane.  I thought it might be a sattelite.  But it was then joined by several others. The most bizarre aspect was that they darted around in different directions in a manner that is seemingly impossible. I am not sure of the number but as stated above, it was 8-10.  The most exciting part of the event was that, after I watched for several minutes, I got the feeling that the objects were aware of my presence, (even though they were miles above)! It was a comforting feeling.  And after a while, they disappeared. I returned the next night to see if they were there again.  A smaller number of them did in fact appear, but the duration was only a few minutes.  I have never reported this before, officially.  I was inspired to do so after hearing Mr. Davenport on Coast to Coast AM.  Thank you for hosting this site.
