I do exactly the same thing and mine does roughly the same as you. Checks I'm in a safe position and moves my hair. I have asked her not to go and she constantly reminds me its me leaving at times like this! She also now stays with me and keeps her hand on me. Sometimes I can be aware of this sometimes not but she now always stays by my side. I tend to panic when I come out of it so she is always speaking gently to me and encouraging me to take my time and stay lying down etc. I would talk to her as mine was really open to doing exactly what I needed. It's been several years now, but these days I lay on the floor when I feel it is going to happen and doing this often prevents me completely blacking out.
