Sleep Paralysis?

hi! posting this because I have been having these really weird experiences and can’t seem to find a name for them (trying to figure out how to make it stop). I will be dreaming and feel really heavy, usually it starts from another dream and shifts to me laying down like I am in the “real” world. I will then usually get a really horrible sensation of someone grabbing me or touching me and try to wake myself up. I have always been someone with bad nightmares so learned how to do this very young. except when I do that in these moments I feel mentally awake but physically very heavy still and tired, i will feel the sensation of trying to move but nothing happens? it is almost like I’m waking within another dream but cant break into the waking world. I don’t think it is sleep paralysis though because I can usually move, it just takes a huge amount of will power to stay awake. my eyes will get super heavy and when I can finally get a light turned on I need to prop myself up for some time or else i will go back into the sleep state from just blinking sometimes. anyways, looking to see if anyone has experience with something like this or any advice on how to get it to stop. thank you so much!
