The 1st time I remember my friend showing up in a dream, we were at a party and I was having a hard time understanding what he was trying to tell me. The next day, a complete stranger approached me at work, told me he was a medium, and proceeded to convey to me the message that my friend had tried to convey.
My father also used a medium to convey a detailed message to me. This one was a guy we both knew, who had previously conveyed a message to my father from his little sister, after she passed over.
So, I’ve learned to take these dream appearances seriously.
