Missing Cassie

This is a very unusual subject and involves the reason of dreams. It has so far been about 3-4 months since she had to be put down.
As my sleeping pattern fluctuates so does the quality of my sleep. Normally a person would into a deep sleep (REM I think). This is where the body shuts down completely apart from life processes and eye movement. At the moment I am not reaching this stage of restfulness (due to something). This means that I am still able to move and talk in my sleep when I am dreaming. This has resulted in some unusual thing happening when I dream.
As I am now subconsciously missing my cat she now appears in most of my dreams. I remember her very well and she acts the same as she did in real life, which means I don’t find out the dream is a dream until I wake up. The dreams are very real and allow me touch and feel again. Not usual in dreams as all senses shut down so you cannot feel pain or anything else until the time of waking up (apart from flying in dreams have not had that explained).
A few days ago I woke up with my arms cradled as if I was holding Cassie as I had been in my dreams in which I had spent the whole night (in my dream) crying over her death.
It seems to me that I need to gat over it consciously and then my sleeping will return to normal. This could hep with the removal of my stress and might explain why the last I got drunk I burst out crying without knowing why.
Anyway this was just to inform you all of my unusual insomnia.
