ive had several dreams were the RCs that i try just dont work, for example in my dream i remember trying to plug my nose to see if i could keep breathing but my breathing stopped so i knew(in my dream) that it was "real," although even before rcing i really thought that i was awake so when i tried the rc i was expecting it to fail, so idk if that was the problem or not. another case is in my dream i was in my bed in my room and i grabbed my phone next to me to see the time and it said 7:38, then i turned it off and back on and it had the same 7:38 so i figured i was awake and went to bed(inside of my dream), it was only when i woke up i realised i was at my grandparents house, so there was no way i could have been at my house. as far as personal dream signs go, all my dreams are different and epic and i cant find a dream sign that even pops up in more than one dream. the only successful lucids ive had is were in my dream i realised ive never been to a certain location and i realise im in a dream. anyways does anyone have any ideas of any non fail rcs?
