I did. When I was a teenager I had a very vivid dream that the love of my life would have certain initials -- I'll say B.R. I wrote it down in my journal at the time.
When I was in my early 20's I lived in a housing co-op, and somehow this dream came up and I told a good friend and housemate about it. When new people applied to live in the house, their applications were pinned on a board for all to see. One day my friend dragged me over and said "Look, this guy who has applied has the initials B.R.!" I was like, right. For one, I didn't put any particular store by it, and for another, I had a strict policy of not dating any housemates.
Well, B.R. turned out to be a great guy who got past my objections to dating housemates, and nearly 20 years on, we're still together.
