I have never received any definite proof (for myself to know for sure) about reincarnation. But I do not close my mind to it at all.
How can I? I didn't believe in life after death either until last year my Misty showed me for 110% sure -hard evidence -that she lives on after "death". So far she is the only one who could get through to me, but she did a damn good job.
How they come back....if they come back -or whether they just wait for us till we cross over too -I don't know for certain. But I still receive Misty's visits and her love over 1 year after her passing, so she is still in the spirit world. My instincts say she will wait for me until I cross.
But yes -we miss them. It aches sometimes. I feel her love, and that is so happy and beautiful, and real to me....but want to touch her fur, sleep next to her, go walks with her, hear her squeaky yawn and her bark.
I have just read your blog and I am in tears. You write extremely well and her story is beautiful. What a great mum you were to her! I do so very much hope she returns to you. Koko
