These sketches are crap, but I only spent a minute on each of them while I was at work and it's difficult to sketch things I don't normally draw, especially when remembering them from dreams a long time ago.
These aren't recurring, but they're my most memorable nightmares.
The really badly drawn wolf on the left... I had a nightmare when I was seventeen. Basically, the dream consisted of me walking through snow (I never seen snow for myself at the time, so the 'feeling' was very confusing). The wolf appeared, blood dripping from its mouth, staining its fur and the snow. I froze, I couldn't move. I wanted to move, but I just stood there. I eventually started to move but I was moving so slow, like... unbearably slow. It was as if I was in slow motion, while the environment around me, including the wolf, moved at normal speed, but in this case far faster than me. The wolf lunged at me, pinned me to the ground and bit my throat, thrashing about as it wouldn't let go. When I woke up, I was shaking quite violently and I was covered in sweat. I slowed down when I realized I was awake, at home and okay.
The second weird drawing, the one on the right, I remember having when I was twelve years old. It was night time and I was sitting in the back of my parents' car by myself, don't know why. Off in the distance was a football field, a grass oval. Far away was this really weird figure. He, or it I dunno, was tall, thin and wore a long, hooded white robe. It was dancing, like... slowly left and right, but it was slowly dancing toward me. At first I was interested and watched, then I got scared. I got scared when I could see the figure in more detail. He didn't have hands, but rather these four, long, finger-like hooks. He was also wearing a mask, the mask looked kinda 'sketchy' and uneven and there was blood coming out of the empty eyes. The blood also stained the robes all the way down.
I tried to open the car doors, all of them, but they were all locked. I couldn't get out. I then tried to open the windows, but the window rollers seemed stuck, so I then tried to hit the glass windows but every time I hit the window, my strikes were so slow and so weak, again the slow motion effect. Nothing was working.
Eventually I turned around to face the other window and the hooded figure was right beside the car, staring at me. It then threw his clawed hand right through the glass and I think got me in the face, that's when I woke up.
