Honestly, I've seen real demons. I mean real in many forms. People, animals, even objects.
I also have made such predictions about less serious things. I woke up at 3:00AM when I was younger and started counting backwards for no reason at all from 4... 4, 3, 2, 1, and BOOOOOM! Transformer blew outside when I got to 0.
I was at camp and some girl ( I'm a guy) was talking and she was like, "Guess what I saw in the bathroom." She was not even talking to me but I piped in and said, "A cockroach on your toothbrush." And she freaked the hell out.
When I was 9 my mom and I went to McDonald's and she ordered a salad shaker. She was shaking it and I said, "Mom it's going to spill." She did not believe me and she kept shaking away and wouldn't you know it that she spilled that s*** all over the place haha.
When I was 19 I went to bed at 5 AM by passing out in my bed. I woke up on the couch downstairs and thought I might have just walked down without realizing it. I walked back upstairs and saw myself lying in my bed. It freaked me out because I touched my chest and felt the pressure. I went back downstairs and passed out and then woke up in my bed.
Driving on the back roads, my friends and I were bored and driving around and we approached a small back town called Olema in CA. I forgot where I was because the town has a 4-way intersection with a blinking red stop light. The power was out so there was no blinking light. The sky was unnaturally blackened. With an outer glow to it. As we approached the intersection we saw 9 humanoids (human looking cloaked beings). I was legitimately scared s***less. We drove hella fast by them and as we were they all pointed at us with their left hand. Their actions were completely in sync. They were faceless. They had a tiny dog which was bare boned and had red glowing eyes. After that happened we were driving and saw deer lining up on each side of the road just staring at us. This is at 3:00AM!!! As we were moving past the deer we traveled at a rate of 45 miles per hour and were able to get about 10 miles away in 5 minutes.... Time slowed down. It was cold outside. After that the last deer that was staring at us was a huge white deer. A Lamborghini with one head light missing (RED) was driving past as this was happening. It was scary as F***!
One more thing. I was driving on the back roads again by myself at around 3-4 AM I looked to my left and saw a dog. It was sitting like on its hind legs. The scary part about it was that this dog stood damn near what I feel is about 10 ft tall. It had piercings and grizzly teeth. It had red eyes and looked directly at me. This all happened in a matter of 2-3 seconds. I thought I was seeing s***. I had to turn around to check it out because it was so unreal. It vanished. A 10 ft tall hell hound just disappeared out of thin air.
I know this all sounds nuts too, but I can't deny what I physically see with my eyes. UNLESS IM ON ACID HAHAHA lol but no I wasn't at all so I can rule that out.
