The English phrase 'lose one's senses' is almost always figurative. Translating it word-for-word as 感覚を失う will sound like a physical loss of sensation. Use 正気を失う or 我を忘れる for the common figurative meaning.
正気を失う emphasizes the loss of sanity or rational mind, often due to extreme emotion. 我を忘れる focuses on losing self-awareness or self-control, often from being absorbed in something. Both are common, but 正気を失う is slightly more serious.
