I haven't exactly had them say the words 'this one can see', but I've had similar things said to me or about me.
One time I was on the threshold of breaking through and I could feel these entities around me so I decided to ask if someone was there. I 'heard' in that familiar way two voices, one was saying 'Come on, come ON! Let's go! Look he's just a baby!' and the other one was saying 'But look he's trying to talk to us that counts for something doesn't it?', then this second voice directed this message at me 'We were just passing through and you startled us. It's not often your kind communicates with us this way.'
Another time as I was coming up hard on a trip, I felt this oppressive presence over me and it caused me to get quite frightened. When I finally 'broke through' I saw an adorable elf boy sitting on the inside of my face playing a prank on me. When he noticed I could see him I could tell it freaked him out. His eyes got big and he stood in slack jawed amazement that I could actually see what he was doing. Seeing him prompted him to sort of just poof out of my vision. Highly peculiar.
