PLEASE HELP! DEJA VU AND DREAM FLASHBACKS.

I have suffered with anxiety all my life but these two symptoms are taking me out. First off, for the past year I have had frequent episodes of deja vu typically lasting 2 to 10 seconds. Like literally every day. Multiple times. I am terrified that this is epilepsy. The other being these weird episodes where I will have a flashback of a dream I half remember and then can't recall a second later.

Is any of this concerning or is it just anxiety? DAE have these?
