(assuming of course where he went to meet the other was still the third dimension" And from a 3rd dimensional POV on earth, yes, in a way, Loki's astral projection WOULD be going on in his head, as far as his physical body on eath is concerned... to support what LokiD was saying.
In astral projection, you leave your host body. So no, it would not just be going on inside his head. It was a vary curious element to have in the film, certainly wasn't expecting something like that going in.
Essentially Loki's consciousness was in a higher dimensional body, or a "spirit body" of his when he went to talk to the other, while his three dimensional body remained in his little Shield hideout, however, I'm sure his three dimensional body wasn't limp, or "asleep" as he probably could have some sort of awareness there simultaneously, but I am getting a wee bit too spiritual here :P
however, it is worth noting, that The Other physically touched Loki at the end there, something that I would expect not be able to happen, unless, The other is operating on a higher dimension as well, and they met in a higher dimension, the two of them.
Or, it was just for effect
Exactly, his consciousness moved into another dimensional body.
I love that scene between he and The Other, it's one of my Top 5 in the whole film. "You think you know pain? He'll make you long for something as sweet as pain" and then you get that creepy hand across Loki's face. Love it.
