It’s not much of a problem, it’s more just a question. When I do an RC for whatever reason, and 5-30 seconds later I see another thing that should prompt me to do an RC, I’m not sure if it’s even worth it to do an RC at that time; it seems kind of redundant.
What are your guys’ thoughts?
I’d say it’s completely worth it. After all, how do you not know that last RC was a false memory from the dream?
Yeah, as far as I know the point of Reality Checks is to constantly make sure that you are awake at that particular moment - maybe you suddenly fell asleep somewhere and end up in dream a little while later?
Thanks guys, that clears it up. 
Haha, omg, this actually answers the same question i’ve been thinking about for a bit now… I’d do a RC then 20 seconds later would have some signal but then think “well… i just did one, i guess i’ll just do it later…”
You don’t even need to worry about whether you are sure you are awake or not, one of the points with reality checks is to become more aware - you use them partly because you want to study your surroundings and feel more present in the moment.
