i can not forget him

I still see the same man in my dreams whom i have no connection now.

I last night had a dream again , this time we were a couple and we had a baby.

a baby that was white and lovely...I tried hard to take care of the baby
as it was very precious to me...

I don't know how long more i will have him in my dreams , i just need help

But the best thing is whenever i see him in my dream something nice happens
the next day in my life, he is like a gospel

If he is just a DC, when you become lucid next time, just focus on going and seeing him. I do this a lot when I want to find someone specific in an LD. Failing that you could always try sketching him, and thinking about him before going to bed.
