Magic Forums

So my friend has just discovered some kind of alter in his house. It was in his brothers room, who shares the room with his girlfriend. At a quick glance it's easy to miss it. It looks like some kind of display of random glass bottles and trinkets. But upon further inspection, you can tell there is something weird about it. Now, I know close to nothing about this kind of stuff, which is why I found this website. What makes me think she's doing some kind of black magic/curse/voodoo is what she has on it. There is some kind of playdough figure that has pins all over it and a little plastic skull between it's legs. She has other skull figurines as well. There are a couple leaves with crystals on them and a little bowl of salt. There was also an empty bowl that looks like she might back been mixing the salt with something else in it. It's just a little alarming that somebody in my friend's home is doing something like this. It might be nothing, but it might be something bad. I we hoping to be able to post a few pictures of it on here, but I didn't see a way to do that. So I figured I'd describe it as best as I could. Any feedback on this is appreciated.
