I have lost my best friend and my little brother. Within a year or two of hoth of them dieing, they each came to me in a dream. That is what I believe anyhow. I have had dreams with them in it but there are also the dreams where they are just talking to u, u know they are gone in your dream and your just happy to see and hear their voice and in ky case I told them about my new son id had since they were gone and whats been going on since they left the earth. To me I truly believe those conversations were real. I dont have proof but I know it in my heart.
