I'm so confused!!

So my husband and I spent the night together for valentines day and this morning at 12:00am technically the 15th of February we had sex and went to bed around 1:00am. Well I told him earlier today when I woke up "I'm gonna go take a shower and last night was great". Then he looks at me funny. I ask him what and to make a long story short he doesn't remember anything!! I litteraly had to pull out the towel we used to clean up just to prove it to him and he thinks I'm nuts! He says he doesn't remember anything! I know it's not drugs, I know he's not messing with me because he swears I'm freaking crazy! I litteraly can tell you everything we did. We watched a movie. I made him food he ate we had sex and everything! He has a history with having seizures and I think this is one of those times. Is it possibly to be completely normal while your having one and just loose time???? I'm like so freaked out guys!!
