Idk if it fits here but my moms grandfather passed away about 5 years age. He was a great gursikh and read a lot of bani. After his death it was found that there were several items under his bed which shouldnt be there (black magic items). While questioning one worker in their house said he kept it over there around a year ago.
Sangat who mention being troubled by such things, listen to Sukhmani Sahib, keep it on in the background while working/doing housework.
If it’s really troubling you, then listen to 1 paath of Chandi di vaar. Just 1 paath per day, it’s too powerful to do more. Do it at amritvela, keep a glass of water and sprinkle it around your house after (remaining water drink it). Once the problem stops (it will stop fast) stop Chandi di vaar completely (really is too powerful to keep doing). But then do Sukhmani Sahib daily and such things won’t return.
