Do you have a carbon monoxide detector?
Dizziness can be one of the symptoms. http://www.nhs.uk/Conditions/Carbon-monoxide-poisoning/Pages...
The poster thought they were being spied on by law enforcement, and that a drone was entering their house and moving around the iPad they had set up to monitor the premises (!). They posted some of the clips to YouTube but none of the commenters saw anything suspicious.
It turned out to be a paranoid delusion caused by a combination of stress, sleep deprivation and Adderall, which is the exact situation in this thread. I would highly encourage the OP to read both the original post and the followup.
The CO one scared me, especially because a few fir alarms went off in my house a few days ago, but my father and I looked around and confirmed there was no fire despite them going off for ~1 hour. Myabe lighting the stove for the first time? Anyway, I think I just need to get more sleep and my parents have been cool about it. I think they are a bit worried, but seem to be resolved to just monitor me, which is good.
Most fire departments also have a non-emergency line that you can just call for advice, they may even send somebody by non-emergent to check your house out and you as well. Some EMS providers (in the US most fire departments have EMS on staff also) have the ability to check for carbon monoxide in your blood.
During my time as an EMT, I saw plenty of people go crazy for various reasons from schizophrenia to completely unrelated physical issues such as diabetes, migraines, epilepsy and rhabdomyolysis. I AM NOT A DOCTOR, but you should consider consulting one. It may not be that you are not "crazy", but you may have some other medical condition affecting your mental status.
Best of luck.
