Cold astral touch? To prevent?

this happened in a dream state but I do not believe it was a dream. Still I have no idea where to place this thread so figured I place it here.

So very short, for me that is ;) : In the dream I felt a presence, it is someone alive who I think was dreaming at the same time. We've had a fall out in real life, not the dream.

In the dream this individual took its hand first stroking on my cheek then did a little hold on my chin as to say get-your-act together. The hand felt very cold, like physically very cold. I woke up.

If I do not want someone to get that close to my body or astral body is me imaging a shield of protection enough? I think I was so tired that I went into this exhaustion of sleep and so it wasn't up?

I could feel this person liking me but having a need to control me, I could feel the control-desire but it thinking it does a good thing by feeling that way.

Anyways, this person got too close. And why is it that it's hand feel so cold?
