Not very often, but during severe mixed episodes if I'm triggered into a rage, I disassociate very badly and it feels somewhat like blacking out. For example I'll be vaguely aware that I am screaming, but everything will feel far away and I won't understand the situation anymore. Then my memory of what happened will be very patchy and fuzzy. I wouldn't say it's a total black out, just very severe disassociating. I've had fights where afterwards I couldn't hardly remember what the fight was about or what happened. Luckily that sort of thing seems to be gone with my medication.
