I've recently moved into one of the oldest standing houses in my town. I've had some experiences over the years, shadows, things moving, noises, electrical things being turned on and off. But I have recently started renting one of the oldest houses in my area and things are 10x more frequent. How do I find out if someone died previously in this house or whether I have the same spirit following me from house to house?

I can not tell if any spirit there but before starting any new thing, like you moved to new place, first of all you should have done cleaning ritual where you are going to reside. If you haven't done it then please do it now.

Old houses are FULL of noises, electrical issues, etc. However, a person does not need to have died in a home for a spirit to manifest there, especially if you believe one is attached to you.

For years now I've felt like there is always someone with me. Shadows walking past the end of the hall, people saying my name, the feeling that someone is watching me. But since moving to this house more is happening and more frequent. I sleep with most of the lights on in the house because 'someone' keeps poking their head into my room late at night and walking up and down the hallway past my bedroom door. My 4 year old talks to people who aren't there and gets cranky with me when I say I don't know who it is she.s talking too/about.

I believe you. This is not an uncommon situation at all. Has anybody in your family ever had issues like this as well?
