Frequency of episodes and how long they last

Hi- When I get an episode sometimes I get what I want to call residual feelings for hours afterwards and sometimes I snap out of it much more quickly but then feel as though another is coming on again hours later but doesn't- And sometimes does- Sometimes I get episodes frequently and sometimes weeks go by
without any at all- And sometimes I simply get stuck in what feels like deja-vue for hours, days, weeks-

Anyone else this way?
