I got to Horsforth roundabout. This was around 02-45am. As I started the approach down the hill, to Rodley, I began to feel overwhelmingly terrified. The nearer I got to the dip in the valley, the more the panic was rising. There was no explanation for this at all. I tried to wake my husband, with no success. I tried to get a grip of myself, to no avail. There were no cars around at all; in fact, when I thought back, I hadn't seen another car on the road, either direction, for at least three quarters of an hour. With the sheer terror beginning to escalate, I was almost at the bridge when I "saw" it. (I say "saw" because I didn't dare look at it directly; I had the overwhelming feeling that if I looked at it, I would die). Stood at the side of the road and looking directly at me, was a very tall, shaggy, brown or black, fur covered shape. At my estimation, it must have stood over 2m tall, around 1.2m wide, with no visible limbs or eyes, but I sensed that the eyes were there somewhere, as I could feel them boring into the car. Needless to say, I had to get away from this "thing", so I accelerated away from it. As I passed, I stared straight ahead, not daring to look left. I looked back in the rear view mirror, to see "it" step off the kerb and into the road where I had just driven. By the time I reached our house, I was panic stricken, I needed to get in and lock the door. My husband couldn't understand what was wrong with me. I explained what had happened, but he said that it was probably a tree and my mind was playing tricks on me! I knew what I had seen and it was no tree.
