I have having the following symptoms for a couple weeks.....I would like to what might be going on. I have been having sleep issues, waking up several times per night, sleepwalking, insomnia for periods of days dreaming/nightmares. I have trouble with my balance (falling), coordination, spelling and when I talk the words I am thing often come out wrong or come out different. Lightheaded, always cold and a random headache in the front left side of my head. Blurry vision. I have also been having some hallucinations, seeing people and items that are not there and items changing colors in my home, my husband doesn t believe me but I expected that and lastly going to the bathroom more frequently, back pains. If you can give some ideas of what this is, I would appreciate it. I am getting scared. Thank you, Desiree Pocuis
