Ok, both can be released with pain and chakra bursts or "clearing your mind" techniques such as elder senses, etc. Anything that can "snap" you out it.
The first one however, will only fully work if your rank is much higher (3 ranks above) your opponent. When the technique was used on tigers next to Anko, lets not forget it was used by Jounins against animals. My deduction is that although it can hinder and "numb" your mind, you'll still be bale to move even if slowly and with difficulty. It pertains only to the ability to move your body. Your judgement isn't, in any way affected.
The second one is different. Its like a pressure, a huge impact as you feel the malice and dark emotions and killing intentions behind your opponents mind. As its forced onto you, your mind is hindered. Fear takes hold of you as you become filled with nightmarish ideas and severe terrors. Now, to fully disable you, your opponent needs to be 2 full ranks higher than you. For example, if you are a Sannin, the enemy needs to be a Sage to fully provoke the nightmarish effects of killing intent. However, even if the rank is equal, the pressure is still there. You'll feel it as you feel heat or other external source of strength. Even if you don't see the nightmares and are still able to move, you'll feel the killing intent and it will affect your reactions and reasoning. It can also be release through bursts of chakra, pain or other clear your mind techniques.
