First Why are you driving? If you are so fatigued you can’t remember getting home, you probably weren’t in any state to be on the highway. Please don’t risk your own and other people’s lives this way. You have a serious problem and you need to get to the bottom of it before you hurt someone.
Please make an appointment to see your doctor. If possible, you need to get a sleep study done to ascertain whether or not your fatigue and strange dreams are indeed from sleep apnea. If they are, you might benefit from using a CPAP (Continuous Positive Airway Pressure) machine. A CPAP machine increases air pressure in your throat so that your airway does not collapse when you breathe in and you get uninterrupted sleep. If you try the CPAP machine for a week and the fatigue and disturbing dreams cease, that’s the end of the matter.
If the sleep study doesn’t confirm apnea or if it does and using a CPAP doesn’t help, please talk to your doctor about whether a diagnostic cranial CT scan might be in order. The sidedness of your dreaming and the multisensory experiencing of the dreams concern me. I don’t mean to alarm you but sometimes disturbing sensory hallucinations signal that there is something amiss in the brain. It just makes sense to at least check out the possibility with your doctor.
Please write back and let me know what you find out.
I wish you well.
