A recent greentext post about an imaginary wife made me think of this.
Have you ever had a dream, where you fell in love with a dream character?
I've had at least a couple over the years that I can vaguely remember. The dreams were so vivid, and the feeling of love for this imaginary person was so strong, that I woke up feeling rather heartbroken and a sense of longing.
Not fell in love per se but I had a dream I was getting married and it was clear my partner and I were really in love. There was a sense of happiness I felt that made the dream feel so real. Was sad when I woke up.
