They come and go like it's a bus station.
I hear people often talk about issues with transient hauntings. They might have lived there a long time and never run into problems, then BOOM! Or, they had some haunting problems in the kitchen with a little girl's voice and then later in the bedroom felt a male presence who came and then went after a week's time.
These transient hauntings are very common. One haunting that fits into that category is the recent loved one who passed on and visited and then over time, disappeared. Different voices, different feelings, different features, different places in the home--all typical features in transients.
I recently talked with someone with the issue of a new entity talking to her child. Some children and some people are simply good receivers of communications from the other side. Like the ghost whisperer, entities will approach and see if the person notices them.
It's like this - You're in Italy and you go up to all the shop owners, speaking and hoping to find the one who speaks English. So it seems to be in the spirit world. Some of us are capable of feeling a presence, others of stopping and noting it, and a few exceptional ones will hear or see them.
When we get transients, we can get beings hoping to make contact, realizing we don't understand them, and move on.
In the case of transients, nothing needs to be done. If you ignore the situation, it resolves itself. There are a few who feel better about opening a Bible or saging a room in order to clear it of entities and that is purely a personal choice. You will also find this more likely to happen when you move into a place that has been vacated a long time, if you have children, if you have recently lost a loved one -- that seems to make you more open to the other side, and if you have undergone major surgery or life-threatening illness. There are moments in our lives, where time slows down for us and we are out of sync with the mainstream, such as depression, illness, grief. Those times are the most often periods we are plagued with transients. Perhaps its our change in perspective of what is important, or changing our routine so we slow down and notice things.
Whatever the reason for transients, all you need to know is that they are travelers in a train station and will move on.
