Ever received a sign from a loved one who has died?

thats cool, I didn't get a sign as such but I did have a conversation will my bother in-law in a dream about a week after he died in a farming accident he was only 29, I gave him a hug and told him how much I appreciate him and how i am glad he was part of my sisters life, it was soo vivid and even 3 months later I still remember it
