Sounds sort of like dissociation to me ... Whenever I'm dissociating I feel kind of numb and fuzzy and in a dream like state ... Does it only happen when you're drinking or has it happened when not drinking? ... Also, did it ever happen before you were on medication? ... While on medication? ... Or has it just started happening as you are coming off the medication? ... All of these angles are worth exploration and discussion with your doctor ...
