hello logan09876, welcome to the forum 
We do have a big topic about SP in the stuff forum (link) but this is for the SP you feel just before going to sleep or upon waking.
IMO the SP is probably leaking through into the dreams due to be being aware at some level to the SP we all experience while dreaming. If you use the search button, you will probably find quite a few topics on moving slowly or feeling paralysed in dreams.
I hope you enjoy your time spent at LD4all
