Any tips on how to wake up during nightmares

I’ve had vivid nightmares for the last 10 years due to antidepressants and on/off cannabis use.

Even if the situation is terrifying, I eventually found peace in knowing I’m getting rest.

Let’s say I wake up now and can’t go back to sleep. It’ll be what, like 2am/3am? Now the rest of my day is fucked. Was it really worth waking up?
