2006 Cook City Montana

I was driving from Salt Lake Utah and decided to go home a different way and my home then was Colstrip montana And it was almost dark going through cook city, but I did not want a motel so went through the city and found a spot I could drive off the road and still be close to the highway as I could see the cars going past however I was off the highway like 50 yards and I layed the seat down in my Subaru and shut off the engine as I was tired and then I was ready to close my eyes when something came up to the second door window and put its head really close to the window and I froze but did not acted like I saw him or it and it was a large head I looked the doors earlier and did not move and it was stooping down to look in and was there a short time then left and I was really tired but that woke me up and I gave it a few minuted to leave and then I got up and started the car and turned around to go back to the highway and did not see another car around so felt it was a bigfoot all the time and got back on the highway and headed home and after about 30 miles felt sleepy again but on a turn off on the highway I went to sleep in the car but stayed in the drivers seat.
