Why do I get dizzy or disoriented when my brain expects something to happen?

Hi doctor,

Can you tell me why I get dizzy or disorientated when my brain expects something to happen but it does not happen? For example, if I try to click somewhere on my computer but my computer freezes before I notice so the click does nothing, it will disorientate me and make me dizzy. It will jolt my vision and make my head pound for a couple of minutes. It happens quite often, usually when I am not fully paying attention. I am 26 and male. I have had this problem for as long as I can remember. Currently, I am taking Thyroxine for Hashimoto's disease.

Thank you doctor,

When it happens, my forehead and the top of my head to above my forehead hurts and throbs. No nausea just dizziness. I have very bad short-term memory. I forget things literally instantly for example phone numbers or if someone tells me their name, I will often forget the name within 20 seconds or if someone gives me new instructions there is no way I can remember it even if it's only three steps. When someone tells me to look at something, I will completely forget what I just looked at 30 seconds later. I thought this was due to my untreated Hashimoto's but now my Hashimoto's has been controlled for six months. I still have these problems, it has not helped at all. My doctor says these symptoms are not from my thyroid as the levels are perfect. I do have anxiety, panic attacks, and I do not know how to socialize. I struggle to talk coherently and when I do talk I can barely think of things to say because of my brain fog. Sometimes, it literally hurts my head to think, literally, not an exaggeration, the middle of my head above my forehead hurts. From middle school to high school, I was in the special education class as I struggled to learn things. Even now I still struggle to learn. All of these specific symptoms started around the same time when I was around 7 to 9 except for the panic attacks, they started when I was around 14. But these symptoms occur when I am not anxious. They occur randomly at home as well as when I am out.
