Assuming that this would cover all past legal names as well (as I have had a grand total of four, different first and last names): still not a lot.
I have changed a lot since I first started posting things on the web, and I am embarrassed about some of the older stuff that I said before I learned more about certain subjects. But (as far as I can remember), the worst comments I ever made were ones in defence of outlawing abortion, and even those I never posted hate in.
So, given that those few comments are vastly outnumbered by my more recent comments explaining why my previous stance was nonsensical, I would probably have to be more afraid of someone threatening me for being a trans person who advocates for bodily autonomy as a basic and inalienable human right.
As someone who has suffered from night terrors and other disturbingly vivid dreams, I would recommend starting to do “wake checks”.
Set an alarm on your phone to go off every few hours at random times during the day. When the alarm goes off, do something that produces a reliable result, like turning a light on/off, turning on a faucet, checking the time on a clock, or pinching yourself. Make your checks as varied as possible, and do them in a different order from day to day, because you don’t want the results to become part of a pattern.
Once you are in the habit of doing that, start doing those checks any time something ‘out of the norm’ happens. What ‘out of the norm’ means is up to you, but essentially any time you think that something is weird or out of place, do a check. What you are doing is training yourself to check whether you are in reality or not.
Once you start doing that, you will probably continue that habit when you end up in a dream. However, these checks will not produce reliable results when you do them in a dream. Turning on the faucet won’t make it give water, the time will change drastically, lights won’t turn on when you flip the switch, etc. These are now your cues to see if you are awake or not. If one of these things ever DOES start to give reliable results in a dream, stop using it immediately and substitute a different one.
Once you have a way of determining if you are awake or not, you have a way to wake up. Most people wake up after realizing they are in a dream, and even if you don’t, realizing you are dreaming should result in a massive shift in what is happening in the dream.
One warning though: if you have night terrors where you end up paralyzed, you will want to have a contingency plan. My night terrors usually started in a situation where I was unable to move, and that is the main reason I struggled with them for over a decade. The only thing that helped there was meditation where I would focus on “feeling” my fingers and toes and how they moved, and then getting myself in the habit of using that meditation as an anxiety response. Doing that in a dream will usually end up waking me up because it forces my brain to focus and eventually move my body irl.
