Hey Lydia,
Just a question, you say you haven't had dreams of him, are you dreaming at all or remembering nothing?
Could be many reasons, one recalling the dreams isn't happening so ask to be able to remember, just like a personal affirmation (excuse spellin!) that you will remember your dreams. try and get good nights sleep as well as this can help.
Also keep setting intent to be visited and make contact. The energy will slowly build up. But br prepared to wait a while as i know you will, when we pass over I've heard sometimes we need to visit the center in the park in Focus 27 i think it is, helping new arrivals get to grips with the new world.
I'm sure he will come see you soon
Ryan
