a question about wild

[chitrarth]

hello everyone i experienced something strange last night i am trying to do wild at night time since more then three months and i know its not good for me because rem is 90 minutes away but last night i lay down on my side and just started watching those hypnagogic images they were bright and they eventually turned into a full dreamscape it was fully wide and clear . within 5 minutes it happened and it was fixed i was observing it that was my own house and some green colored magic waves were also their moving around i knew that i was about to enter that dream but my arm started hurting a lot so i opened my eyes to relax my hand and again start but it didn't happened afterwards .i know i was very close to a successful wild .the day was normal except one change i slept for two hours at daytime. my question is if we sleep at daytime REM occur directly at night without waiting for 90 minutes or does it make any difference? and one more thing is my schedule only allow me to do wild at that time i cannot do WBTB that is why i am doing at night .
