Hi and to PC!
Odd thoughts, that start suddenly but dont go away and are confusing to your known reality should not be ignored. If you dont already have a T and or Pdoc, you should really find one, a profession would be able to help you figure out best where,and why these thoughts are occuring... sooner is best too because invasive thoughts can sometimes take root deeply if unattended and cause further confusion and distress. Keep writing here for support as well! Hope everything resolves easily
