I Need Help.....

[Jess Emerson]

I woke up to a loude screatching the other night and I found claw marks on my legs I also saw blood on the walls but it went away when i blinked i thought i was seeing things I'm kinda freaked i was so scared to sleep in my room when i was visiting my mom do you think because my energy is so strong in my famly that an entity came into my room feeding off of it when i left?

Most likely yes, but im not completely sure what creature would have the motive to attack you without a cause.

Another idea is that it could have been trying to tell you something important, like the house isn't safe...or it could have been for no reason at all.
If your presence got the attention of a mischievous spirit,
it might have just decided to poke fun at you for no real reason...some get a kick out of scaring people.
Did it's presence remind you of anything/anyone?

I've experienced something like this myself. More often than not, it is someone who is trying to contact you for something important. In a lot of cases, it's pretty negative. For example, the one that attacked me was the spirit of my ex girlfriend's father, who tried to strangle me because I broke up with her. It went on for several nights before he finally backed off. Still, the point remains that in your case, whether or not it's a message is based on whether or not the presence feels familiar to you.

Listen... I know you probably do not believe in God, but pray. I've had the same things happen, and He can protect you and send them away. They won't like it, but they will.
