Bright light came up behind me, next thing I knew I was in same spot, vehicle still moving and over 2 hours had passed.

I had gotten off from work in Mpls at noon to surprise my mother with a weekend visit who was at her cabin outside of Ely, MN on Burntside Lake. I had made great time. It was fall and getting dark early. I was driving my el camino (about 70 mph) and looked at the clock. It said 2:22. I thought to myself, I only have an hour and a half and I'll be at mom's and it will still be light out. Immediately after thinking that I noticed a very bright light in back of me - about 1/4 mile behind me. I thought it had to be a motorcycle. 5 seconds later it had cut the distance in half. I thought it'll pass me, so I sped up. I was approaching a curve and it's a single lane road and I wanted to be around the curve before it tried to pass me. There was a deep ditch on my right and ledge rock/granite 12'-15' outcropping. I glanced in my rearview mirror - now the bright light was right on my tail. Just seconds had passed. The light was so bright I could not see what was behind it or to either side of my vehicle. I remember the noise of the radio and the announcer saying it was 2:23 and the news would be on shortly.
The next thing I knew, I was in my el camino, still going 70 mph, at the exact same spot ONLY IT WAS DARK OUTSIDE. The radio announcer said it was 4:30 and the news would be on in 30 at 5. I looked in the rearview mirror and there was nothing behind me and nothing in front of me. Nothing had passed me. Not one thing had changed except the "vehicle" behind me was gone, it was now total darkness, and I wasn't going to make my mothers in daylight. I have no idea what happened. I felt fine, but weird. I was not hurt. I was not tired or sore. I was not sleepy. Just weird - like wtf just happened. I have no idea where the time went. I know I did not pull off the road for 2 hours. I had not done drugs. I remember every thing up to and after that 2+ hour time frame. I just knew something strange had happened. I also knew I had not been in danger.
The next incident a couple years later, I was coming home in the winter. My husband and I had moved to Ely on Burntside Lake. I had been to a quilt club meeting. On my way home, about 8:30pm, in the winter so it was pitch black out, I came to a part on the gravel road next to the Lake. The moon was full and on the east side of the lake. It was beautiful so I stopped in the middle of the road. All of a sudden, between the moon and my car, up in the sky were a series of lights. A series of 8, one at a time, right after each other, repeating over and over as it travelled across the sky. I could see nothing except the lights, so I couldn't tell the shape or the size of the object. The repetition of the lights did NOT reflect on the water of the lake - I noticed this because the moon DID reflect on the lake. I stopped watching and went home.
I still live here. Sometimes I feel like I am being watched - not often - more like something is checking up..............probably my imagination. The remainder of the "Characteristics" and "Close Encounter" only applies to my first encounter.
