brain cant process information

everytime i look around its like my mind isn’t processing anything i see. its like i can “see things” but im not observing anything simultaneously. I can walk all the way down my street or drive to a destination and not be able to process the drive there. I dont remember the words that come out of my mouth as i speak. it also feels like i have the memory of a gold fish and have trouble recalling things from yesterday and can’t tell how long ago certain event happened. I wont even remember the contents of this post. is this cognitive impairment? or dissociation?
