You were so busy coming up with a plan, that you hadn't noticed the fact that your cylinder-shaped body had stopped moving.
The pig, despite not knowing what was going on, realized that you hadn't disappeared after it pushed you away.
It already saw you as an enemy after you tried to take back control, so it wasn't going to let you go, now that it knew about you.
You were still resting and hadn't expected the pig to even become aware of you, which meant that you were completely open to it's attack.
It slammed it's consciousness against yours, trying to push you away with brute force. The attack would have been a pathetic attempt in your eyes, if the pig hadn't started it with the considerable advantage it already had. You tried to resist, but it kept pushing you back,
until you had been shoved into a distant corner, even more exhausted than before. It kept trying to push you away, which you were now helpless to resist, but soon realized that it couldn't get completely rid of you. The pig had gotten used to being the one in charge and had even chased off some of the people that took care of the pen before. Things had always gone its way, so the fact that it couldn't get rid of you made it angrier than it had ever been. If it couldn't get rid of you, then it would show you who was in charge.
The pig didn't think in words, so it tried to use feelings, images and ideas, together with it's continued pressure to make you submit.
You were bombarded by the pig's crude thoughts, as it pushed into your defenseless mind.
It couldn't see you and instinctively tried to figure out what you were, based on your memories.
The pig couldn't understand most of it, but figured out that you were female after a while and immediately changed its approach.
It didn't see you as an enemy anymore, it saw you as a rebellious sow, unwilling to submit to it.
You noticed the thoughts being forced into your mind change from agressive to lewd.
Images of sows being bred by the pig flashed through your mind, accompanied by the pig's thoughts,
which only had pressing you down on its mind right now.
You tried to press back against the pig's thoughts by making it clear that you were not a sow, but the pig seemed to think otherwise.
It immediately pushed away the resistance you had somehow managed to build up and forced itself into your mind again.
The pig started shoving images and thoughts of you being a sow into your mind, turning it into a mess.
Everything that came from the pig was crude and easy to distinguish from your own thoughts,
but the sheer quantity occupied you entire conscious mind, making you unable to think of anything else.
Things had turned competely one-sided, with the pig filling your mind with whatever it wanted.
Anything else was swept aside by wave after wave of thoughts and images, crashing against your mind.
It finally stopped at some point and decided to rest, knowing that you couldn't leave, the same way it couldn't push you away.
The pig had even stopped panicking about its body, after all, there was a sow for it right here, so it didn't really need to move for now.
It retreated and left your mind behind in a complete mess, that you would need to organize, after having rested enough to do so.
