well i have been staying at a friends house the past couple of days and stuff like weird sounds (scratching/moving/thuds) and we see shadows from small to very large. Also three days ago my friend found an unexplained single black rose pedal. Sometimes it feels really weird there like its not the same place. This morning she woke up and there is what we think to be a bit mark.

Hi hon! Why don't you start at the beginning and explain as much as you can in detail. There's not really much to go on here to help you and it does really help to have details. A good idea for your friend, if this has been an ongoing problem, would be to start a journal and keep track of things that have been going on. Also take pictures of any marks that are suspicious. Good luck and keep us posted!

thank you i will start a journal and i am trying to get a camera too i will keep up to date whenever anything happens we have tried to record sounds but are laptops for some reason wouldn't record even though it was running fine i just didnt record anything not even us asking questions

Angel has a good point, more information is almost always better. But if you are asking questions or challenging this 'being" then you could very well be feeding it. AKA giving it exactly what it wants.

So my question is, what have you done so far and what do you know?

3 great rules to follow:

Ask for help (spiritual or physical)
Never Challenge (tell a being that it can't "do" something, or call its bluff)
Leave if possible
