Did I have a wet dream.

Last night in the early hours of the morning I orgasmed but I don’t know if it was due to a wet dream or masturbation. I have this vague memory, almost dreamlike of me masturbating. But it felt so real. I have this vague memory but not of the buildup or the aftermath I normally have when I MO. There was no guilt or a sense of failure due to losing my streak (which was at 3 days) just the confusing thought “did this really happen?”. Still not sure if I should reset my day counter.
