I can only speak on subspace and the few times i have actually been there but heres my two cents worth.

 

When i have gone into subspace its been like being in the most warm, safe, secure place you can possibly think of being but theres nothing other than being fully aware of everything and nothing at the same time. i can hear Masters voice speaking to me low and soft, i can feel the blanket He wraps me up in i can smell the fabric softener and His scent but im not "there" all these things come to me like im in a dream or watching a movie in slow motion. what i can fathom is the most profound peace, no pain, no fear, no stress of any sort. Hmmmmm perhaps as if im back in the womb? Master has said on more than one occassion that He thought i had passed out or fainted but to me i was still "there" but not. Its the most amazing thing i have ever experienced other the births of my children. Cant wait for Master to want to play again soon. ~soft giggle~
