Butterflies are your dead ones is my favourite belief in this culture

Not exactly every butterfly but ones that is on your house or follows you, I believe this very strongly cus the other day when me and my bf were eating lunch together a butterfly flew into my bf's hair, I tried to remove it but then it like did this cus idk how to explain it

anyways yeah my bf told me it could be my ex and I believed it, I asked the butterfly if "is this your way of giving us your blessings? If so stay in this ring if yes and if no fly away" then it didn't leave throughout the whole time we ate. Only time we left the place it flew away
