My friend, I don't think any of us know how the spirit world works but I can tell you this, having a NDE- Near Death Experience in 2006. When we die and reach Heaven (spirit world) we do not want to come back. I was dead just long enough to learn a few things. We will recognize our loved ones on the other side - they will not look as they did here on earth but we will know who each one is, if this makes any sense.
It is not as much what is seen as it is the feeling that you receive. It is something that no works can explain and I feel that is much of the reason we do not want to return. I had this feeling over a year after leaving the ICU unit and still can pick up on it every once in awhile.
I also feel that you are right saying that your brother misses you, and you are tapping into your heart where your brother also lives on. My friend you have found a way to reach out to your brother and by all means do not stop. There's many people that can-not.
Remember this, it's only temporary and you will again be reunited with your brother. Chap

i do believe that when we leave this world & go to heaven we will b reunited w/our loved ones. i talk to my best friend every single day, sometimes all day long, i don't care if ppl think i am crazy, i know he can hear me, i find little signs of him after i am going through things that i talk to him about to remind me he is still listening. don't think that u r loosing ur mind b/c ur not, he is w/u in ur heart. someday ya'll will b reunited again. my thoughts & prayers r w/u.

i talk to my son all the time. i can feel him around me, its impossible to put into words. the closest i have come is to say that i can feel not only my son, but my husband and my father around me, and its more like they are nurturing me, a feeling of them smiling at me like a parent looks on their child. i know what you mean about sleep. i just talk to my son and ask him to help me sleep and then when i wake up i ask him to help me get thru the day. works everytime.

I talk to my daddy all the time, I do this by writing in my DADDY JOURNAL, I feel like when I am writing in this, that he is right there beside me. It has helped me alot!!!

I constantly talk to my daddy,and I know in my heart he can hear me. I really feel you had a wonderful moment last night - treasure it forever. And also try and open your heart and mind up to him more often.....its a great comfort.

I constantly talk to Ted, out loud and in my head. There are times I lay down and just start talking in my head and fall asleep. When I feel a meltdown coming I've just let it come then let the exhaution flow to feel a peace. Later I seem to feel as if it was an inch towards moving on. This probably sounds dumb, but has been one of my observations as I think back. Thanks Chap for the insight of NDE.
