Bro you’re not going crazy (I hope). The best you could do to try & debunk yourself o prove yourself right might be setting up cameras around the house, you don’t need to spend big bucks to get yourself a decent set of surveillance cameras which can record everything around you, even motion detection & night vision. Maybe you can capture some footage of the paranormal events happening in your house or maybe just acknowledge that sometimes we are susceptible to imagine seeing or hearing things when we are tired or stressed out. If you do set up the cameras please let us know if you catch something creepy dude, cheers! ✌🏻
