Anything that was a major thing in your life, good or bad, can be missed in some way once it is gone. The trick is to remember that quite a bit of that feeling is missing the predictably of daily life, not necessarily missing the thing itself.
I was also kicked out, though it was during my college years, and there are still times I find myself missing my parents, even almost 10 years later. The feeling isn’t as strong, and it is mostly just me lamenting the fact that I will not have a lot of experiences most people consider universal, such as having family to visit for holidays, or having someone to talk to no matter what you have going on in your life.
It is a bit like grief. The parents you thought you had are gone, even if they are physically living, and you had no choice in the matter. The feeling will come and go, it will change over time. But it will get easier.
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.
