why do I still dream about you

I don't understand why he's still come in to my dream...
Around my ex boyfriends, he's the only one who still appear in my dream..
I don't get it either, because we never see each other for long times..
last time we met was around year 2008..
and the last time we had contacted was around 2010..

So it's quite long..long time..

Maybe at that time, my feeling for him was quite deep and so meaningful..
We had a strong love bonding at that time.. which that caused he's still lingering in my unconcious thought..

It's not that I still have a love feeling for him.. no..no at all..
He's just a memory.. A wonderful memory in my life..
a
Memory that will always remember as one of my beautiful ones..
Moments to remember..

So How are you..? ^^
