Something like that kept happening when I was 8-9 years old. The closest I can explain is with: https://en.wikipedia.org/wiki/Alice_in_Wonderland_syndrome . I kept feeling like Gulliver as either in Lilliput land or in giant land. It filled me with dread and I felt that I couldn't talk. When opening my mouth I felt the motions really slow and it took forever to create words.

Rarely, now in my adulthood I start feeling similar but I realize what is happening and I can control how the objects turn big /small.
