I have mild hallucinations. Pretty regularly I have odd physical sensations, like the skin on my legs is sloughing off or very convincing body dysmorphia. Stuff like this is worst when it keeps me awake. Exercise or a hot shower tend to fix this.
When I am really stressed out I have some auditory (usually more or less ambient noise) and visual (usually motion at the corner of my vision) hallucinations. The visual/auditory hallucinations usually only kick in when working 50+ hours a week for extended periods and worried about personal things. To minimize these periods, I work super hard when I am working and try to keep complications to a minimum. I'm sure it has held my career back somewhat not to have the same capacity for work hours as others. (Yes, 50+ hours a week is minimal for a lot of people, but for me I need that extra time to relax and recuperate.) The last visual/auditory hallucinations I had were pretty recent. The past couple of months required some 60ish hour weeks, I had a good deal of disrupted sleep and my wife had some health problems.
I have strict routines. When they are broken I tend to get upset. For example, I have a rigorous exercise routine. When it snows and it makes it harder to get to the gym or out for a run, I get disproportionately angry. I eat things in a very particular way, if someone disrupts this I get angry and will probably tell them about it.
I don't like it when people repeat what I say unless I explicitly give them permission. An example is that my wife might discuss something with me and then discuss that with someone else, and include my view on the subject. That upsets me.
I do not struggle much (at all?) with paranoia or catatonia.
There is some more, but I'm not super comfortable sharing in a public venue where potential future employers are likely to see.
I recognize all of these things are not normal. Over the years I've built up a good set of filters that keeps most people from even noticing. That's not to say I bottle up the reaction, it's just that I've built in some mental processes that help keep the keel even.
