Lots of people don’t remember much of their dreams.
I wouldn’t take dream recall as a good indicator of sleep quality…
Stress could be causing lack of good sleep though.
You’ll need to get past that fear at some point.
I don’t see the need.
Honestly, the first place you should start would be with learning some kind of banishing, do some return to sender spell, take cleansing baths (salt), and try to keep yourself and your space energetically clear and grounded.
It might also be a good idea to call on the Luna Servitor to help you do a lot of this.
