question about sp

i know this is going to be one of thoes “its different for everyone”, but is there an advarage time SP lasts because i went to do a WBTB and WILD at 9:30 and when my cat jumped up on me at broke my concentration at 10:45 i had yet to pass SP and go to a dream. also when i woke up my legs where still paralyzed for a good 2 minutes! i could move eveything but them.

well i myself, dont really notice how fast time passes. it seems it goes faster the more realxed you are
