So lately, I have been seeing more spirits. I cannot decide what they want, all I know is that I know them from a past life by talking to other people. One night, it was around 3:00 in the morning. I had woken up from a terrible nightmare. Out of the corner of my eye, I saw something crawl across the floor. I tensed up, but having just awoken from a nightmare, I let myself relax thinking that maybe I was still seeing things from my dream. So, I layed back down, and fell asleep. I had only slept for about 40 minutes when I was woken back up by the same nightmare. I sat up in bed, trying to comfort myself by petting my dog. Then, she started barking at a space very near to my closet. I reluctantly looked over, only to find a human shape turned towards me. I kind of freaked out. It raised a hand to its mouth, and I heard: Shhhh! I almost passed out, i was so shocked. I looked down at my dog, who was whimpering. When I looked back, it was gone, so I lay back down and went to sleep, still having the same dream as before. The next night, before I even had the chance to fall asleep, my dog started whining, and was again looking at the same spot as the night before. When I looked up, there were 2 people talking to each other. They each wore black hooded cloaks and were whispering. Here's how the conversation went. i will name them 1 and 2.
1:This is her?
2:yesssssss. (I say yessss, because it was said with a snakelike accent)
1:She is different
2:I am sure.
1:positive?
2:she is yoursssss
Then, they were gone, just like that. One of them has been returning each night. I have gotten used to it, so that by now I am totally calm with it. But, it still is a little creepy. I am absolutely sure by now that it is more than a ghost. It seems too smart, and not emotional enough. Advice? Should I be scared?
