Thank you for responding to my query. Your comments and thoughts were most helpful. They've put me more at ease with the 'fleeting violent visions" I've been experiencing.
You said: "Being on a spiritual path, the thoughts of having killed/maimed/tortured are a bit . . . disconcerting, no?"
You bet they are! And I love your idea of "tapping into some warrior past life stuff." Possibly the spiritual warrior I've become these past 5+ years has coaxed these 'fleeting violent visions' (from past lives) up to my consciousness to support my soul's return to 'balance and atonement'.
This encourages me to accept/embrace these visions rather than resist or get anxious about them. Hmmm... More for me to explore here. Thank you for pointing me in a new direction.
