Voice changes

Has anyone experienced this: my voice will change in a second. I go from my normal voice to sounding like Mickey mouse. Nothing hurts. I can swallow The time frame lasts from minutes to hours before my voice goes back to normal Funny story. Was in a drive through went to order food and they wouldn’t take my order told me to have my mom order. I pulled up and had to order They just looked at me funny. My voice gets pretty high pitched. I thought I should do voice overs for Mickey when it happens but it’s random. Lol
