Anyonw hear a weird whistle sound that not everyone can hear?

This may be a little long but bare with me I would truly appreciate some answers. I have a strong Christian faith and use to be not scared of ghost or anything paranormal, nor believe in really weird stuff like this, but ever since I moved into my boyfriends house I've been experiencing a lot and it's starting to get weird... it started with nightmares and that someone was trying to get me or my kid. Then one day I was getting ready for the day and I look in the mirror and I saw on my towel there was a little hand print... I have no idea how it happened I tried to make the same impression but it didn't happen. I took a picture of it and showed it to my boyfriend and his mom and they thought it was weird. I go up to show them and it's still there and my boyfriend put his hand on it and it was a lot smaller then his hand. He kinda didnt believe me that I didn't do it too. So I put my hand on it and it was even smaller then mine! And I have freaking tiny hands!!! And it definitely wasn't our kid cause she was 6 months at the time. The hand print was like a 4 year old or something... idk but I kept it where it was and the next day it was gone.., of course... 😭 For a while I just had nightmares and woke up around 3 -.- and wouldn't sleep the rest of the night. So I started getting cranky. I then hear a little weird squeak sound and I thought it was a mouse. That kept me awake so I made my boyfriend check it out but he didn't even hear it cause he was half asleep so he couldn't find it. We eventually moved out of that room and I put up a dream catcher and have a bible and a cross on my night stand. I no longer had bad dreams nor hear that weird squeaky whistle sound. Sometimes I hear it but it's rare cause I started putting a noise maker in our new room and it made it go away. I kinda just started to believe that it wasn't real and i kind of no longer had a fear of anything paranormal. Well me and my boyfriend and daughter come stay at my mom and dads house while they are away on a cruise. I start to hear that whistle sound and I was like that's weird... it's both at my mom and my boyfriends house. So I say to my boyfriend "hey how weird is that whistle sound being here and my parents house. And he of course goes "what whistle sound?" And I say "the one that's happening now..." he just looks at me like wth is this chick talking about... So this weird whistling sounds starting to freak me out again since it's following me and I hear it again... I've also heard ringing in my ear that's super high pitch, I've also had really bad memory now, and recently I've been having dizzy spells... idk if this is a weird health thing. Or if something weird is going on. All I know is I want it to go away and stop, and live a happy life with my boyfriend and kid, because all this is making a lot of struggle in my life. I am typically a happy person but recently been have been feeling really sad and angry.. any suggestions that won't freak me out to bad lol?
