My mam totally believes in spirits and its always sort of rubbed off on me, I don't know if I'm being paranoid or if there's any chance what I'm thinking is possible. So in 2010 my nana died shortly after that my dad began to have an affair before it was discovered what he was doing I began to see a lot of green cars, green was my nanas favourite colour, I believe the sheer amount of green cars were away of her telling us what was going on Now lately I've started seeing a lot of green cars again I believe its another message, dont believe its anything to do with my dad and I don't know what it could be Could it be her sending me a message or am I just being stupid?
i wouldn't say you're being stupid, but i also definitely wouldn't say a dead person is telling you something by painting random cars on the street.
Green cars aren't ever going to be a satisfying message. If they remind you of your nana that is totally positive. But your nana is in you. You don't have to look elsewhere to find her. You can talk to her any time, day or night, and if you listen really closely to the wind, she might talk back.
You aren't paranoid ,you are exhibiting what's known as confirmation bias 'What you seek you shall find'
