It's so comforting to read everyone's experiences.
I too have had several "synchronicities" regarding my father and his passing.
(A little background)
For starters, my father was my best friend. He raised me as a single parent and did anything and everythinng he could to provide for me. It was NEVER easy and I saw many times, how it took its toll on him.
With that, over the years we really developed an amazing bond. We loved nothing more than just sitting around, relaxing, listening to music over a beer and wax philosophical topics. We also loved to go camping - something about endless stretches of a starlight sky inspired us both.
So... Best friend. Father. Both irreplaceable and both taken from me when he died.
He battled PCNS lymphoma for eight months. I saw the cancer take the strongest man I ever knew and reduced him to an empty shell.
It's been less that three months since he passed away so I am grieving heavily. Yet, in that time, I've had some amazing experiences.
Like you, my first "message" came to me in a dream. It was about a month and a half after he died. In the dream, I went up to my room to do some routine chores and cleaning. After tidying up everything, the last thing that needed to be done was dusting the wooden blinds.
As I approached the window, I noticed something immediately - the light that was coming through the lines of the closed wooden blinds. It was a beautiful golden hue and was warm.... so amazingly warm (despite the blinds not even being opened).
I felt like I'd stepped into the light of the most beautiful spring day.
As I finished the dusting, I turned to walk out of the room and noticed my father, asleep in my bed. I felt my stomach drop through my feet and that instant anxiety that follows.
"Dad??? Dad, is that you? Did you come back?"
His eyes fluttered open and he smiled at me once, smiled again, and then I woke up.
Metaphorically, I think the room cleaning is symbolic of life. As I could not open the blinds, I wasn't "allowed" to see anything beyond but the smallest slivers of beautiful light. I consider this to be a gift of glimpsing what comes AFTER "our cleaning is done".
There are other experiences, I've had but don't want to make you read a book of them. *smiles* If you want, drop me a message and I'd be glad to talk.
All the best.
