As creepy as it may sound, your pets such as dogs and cats are capable of sensing paranormal activities in your home. You may feel nothing, or sense the presence of someone who is not at all close, but it’s very likely that your pets could see them and they understand the difference between living and dead.
This is why they sometimes create a huge row, barking or purring looking at the walls or roof sometimes, and even when they are sitting all alone in an empty space.
However, this is not all that troubles your pets. In fact, if they are making reasonable noises, there are chances that they may have some bodily issues. Sometimes, they might feel terrible pain in some inside organs of their body and are not able to convey this. They may try to heal themselves by licking at the spot, but it hardly helps and they make unreasonable noises.
In any such case, if your pet is making any unreasonable noise, you need to take it very seriously and take your pet to a vet. Get them tested even for some unreasonable behavior because this could be an indication of an underlying disease. And it is important to nip these things in the bud before they create issues in their body.
But if your pets seem fit and fine and they are still making undue noises, try to calm them down and ignore anything that looks unnatural in your house, even when you feel the presence. Unless they make some visible actions, trying to let you know of their presence, do not take any action against paranormal activity.
I know that in this age of science, believing such things is difficult, but these are as true as the air you breathe, even when you cannot see both these things, but could only feel both of them. Try to respectfully ignore these things and change the room of your pets or whosoever resides in there.
