You need to reflect on what you did during the day to recall your dream. In most cases people dream of what they had seen or thought during the day. This will give you a better insight.

Recall Walker Day

I remember _______. I remember you. I remember her. I remember that day. Or you can use the word "recall" instead of "remember". I recall the facts of the case. I recall that she said "no".

I don't recall daydreaming ever being good or bad for health.

I assume you are referring to the Second World War? If so, then if I recall correctly the answer is Victory in Europe Day, or V-E day, for short.
