Paranormal activity happening in my home.. how do I get rid of it?

Ok it sounds crazy but I truly believe in this stuff. A few weird things have been happening.

Let’s start off like this, a few days ago me and my step mom we’re talking about what’s been happening to her in their room, she mentioned she was taking a shower and heard a woman humming like she was singing, she also mentioned when she was washing her hands in the bathroom, there was a cat bowl on top of their tv stand and it was thrown off the weird thing about that is it’s one of those cat bowls that have the rubber on the bottom so it won’t slide

When she was telling me that story, all of a sudden the fan turned on by it’s own, it was half way plugged in tho but it was strange how it decided to turn on at that moment! So now last night we all made dinner & by the stove when we reach over our bodies always accidentally turn on the burner without realizing it, I do remember reaching over and felt my body move it a little but nothing was on, later on they told me the flames were on and I don’t understand why or how. Also when we were sleeping, the cat bowls and the water bowl was thrown, everything was thrown and the food was everywhere. There’s no way the cats will be able to do that.

Then again last night when my husband went to work I brought in my 3 year old son to sleep with me and my 1 year old, a few times he kept tapping my shoulder and kept pointing in the corner, he even put his hands like a claw (you know when kids see monsters they do that with their hands and say rawr) then he tapped me again to point in that same corner and this time he was smiling as he was pointing at this corner

My step mom even mentioned she’s seen black shadows. Now I’m really paranoid, not only for me but for my children. I want these spirits completely gone but I want to do it in a peaceful way so I don’t upset it. How do I get them to leave? I can’t even sleep at night cause I feel like I’m being watched. I really can’t handle this. Someone help me
