When should i reality check for my dream sign?

i dont have a specific object that is my dream sign, but for me it is the setting. i find that I am never in a place that i recognize and that my dreams are usually in some absurd setting. i understand that if you had a dream sign of a phone or something, you would just RC whenever you see a phone, but how should i RC for something such as a really random setting?

thanks

Don’t just RC for DS, RC for anything and everything. Try to train yourself to RC every time you walk through a door, or just do random RC’s during the day. However you do it, make sure to really doubt reality every time you do one so the habit will bleed into your dreams.
