My mother has lived in her flat for approx 6 years and has always had a sense there is something there. However over passed couple of months this has become a scary situation. There is a lot of noise and voices although you cannot make out what is being said. There are little pockets of lights and there is heat over her face. The other night it felt as if something was pulling her legs and it lifts the blanket and touches her feet.

My 12 year old son stayed there last week and said something touched his arm twice he knew nothing about what had happened to my mum.

She has various advice what to do

Salt around the bed etc
Blue candles and saying the lords prayer

The old man died in the house before my mum moved in and his wife had died a few years earlier and her ashes are scattered at the front of the house

Any ideas I am so worried as this spirit seems angry about something

Sounds like you do have something, but as long as it's not hurting anyone you should be safe. If you really don't want them there you could suggest a spiritual cleansing of the house be done. Yes, the salt is a very good idea. Also, just stating that you don't want it there sometimes lessens the activity or makes it go away completely, but I can't make any promises there. You can try putting a tape recorder or digital voice recorder in the room- when you play it back, it might be a little easier to understand. Hope this helps.
