Yes, I’ve been having nightmares, and even sleepwalking, all very obviously connected to the war in Ukraine. I have leapt out of my bed several times (still asleep & disorientated), convinced I’m being attacked by missiles.
I have reacted in this way to stress several times in my life, so I am not surprised world events are affecting me this way. I see that you don’t think your current sleep disturbance is connected to the international situation, but perhaps it may be?
I no longer watch or listen to the news in any detail, and I think this is helping.
