I have about 3-1/2 months post RAI and for the past 2 weeks have been having very vivid dreams and I can remember them for days. The strange part is that they have my mom and dad in them who are as clear as a picture, but they have been deceased for 7 years and I have not dreamt about them for years. It’s really weird. I am NOT on any medication as of right now. Hopefully, will be on synthroid soon. Anyone else experience this who was not on any medication.
