Does thinking about hallucinations make them worse for you?

Does anyone especially see hallucinations when they think about it? Right now, the only thing I see besides flashes of light when my eyes are shut are fast bug like zips across the ceiling but I can almost make them happen if I am thinking about it… whereas if I am not really thinking about I generally don’t see as many.

My so called hallucinations typically show up in a grand fashion that no one can doubt their arrival. There comes a wave of darkness, like a cloud cover that darkens my entire house-only. The rest of the neighbors keep their sunshine.
For a long time it was just the reverse, the entire room I was in would suddenly take on a brightening light as if someone turned on 10thousand lights.
Then just as quick, the temperature would drop to freezing, no matter what time of year it was, I’d be shivering.
Next, what sounded like a huge metal gate would be opened.
Then the windows would “crackle” and snap.
I could hear footsteps on the hardwood floor, and see shadows of people? creeping closer, talking could be heard, the same man (?)and woman’s (?)voice that dominate the house, but no matter how long I stayed frozen in place, No one ever appeared in front of me.
