The feeling of being watched in Presque Isle County, Michigan

I had went for the evening to relax in the nearby harbor (Presque Isle) to have dinner and then drove up to the New Presque Isle Lighthouse and parked my car. I walked thru a clearing of trees (east) from the lighthouse towards Lake Huron. It was a full-moon, clear night with very little waves on the lake. I had been at this location for around :30 minutes to about :45 minutes and had been wading out in the water to just cool off. I was in shorts/t-shirt and flip-flops as it was summer. After I decided that it was time to leave I started to go back towards my car and subsequently dry off. As I was walking back thru the same clearing that I had come from earlier I could hear some motion in the trees to my left. I remember also it was very still/quiet that night while on foot. At different times I heard what sounded like large (or fairly large) twigs snapping on or near the ground and thought maybe it was a deer of some sort, probably not a bear I didn't think. Sometimes it would be one or two twigs/branches snapping, other times it was multiple snaps which would occur quite quickly as if perhaps (at the time) whatever it was had some good size weight to itself. I had the distinct impression (or sense) that I was being watched and it made me feel quite un-easy, I had a more sense of urgency at this point of just wanting to get to my car and leave. Also at other times I heard what sounded like whole trees being moved or pushed somewhat out of the way, I was puzzled as it implied to me that something was off in the trees that had a fairly good size body mass. As I continued on towards the end of the clearing, the sound would parallel (or stay) with me--it wasn't getting distant or going away from my vantage point of where I first starting hearing the commotion going on. After I had gotten into my car I felt hugely relieved but couldn't still necessarily understand why. I remember too, that I was constantly looking around "over my shoulder" very intently but figured it was more than likely a small animal and no big deal. As I drove off (about maybe--? 50-100 yards) as I had already turned on the radio and was feeling pretty relaxed I noticed from off the left side of my car (from the headlights shining onto some of the trees and roadway) a large black, furry looking figure standing completely in the front of the tree line looking dead, straight at me with some powerful--menacing eyes. (The eyes followed me as I went past). It completely shocked me, I slammed on the brakes of my car and just sat in the middle of the road for around half a minute (or less) and was trying to figure out (rationalize/take in) what I had just seen. It stood around I would say between 7'-8' feet tall and it's arms were unusually long. More than anything, the face is what spooked me and I remember the most as it closely resembled that of a man--the nose was flat and it stood completely erect, was not slouched or bent over--exactly still. The head looked like it was just perched onto some huge shoulders, the shoulders were massive going across and the upper torso was quite impressive. I decided it would be best to just keep going as I had thought about of maybe turning the car around and shine my high beam lights into the tree line (to see if I could spot it again) but decided this probably would not be in my best interest. I went on and headed back to Alpena where I had come from originally. I was never so glad to see "city lights" again until I reached the north end of town while on U.S.-23. I told no one what I had seen, actually for a long time.
