Some image I found when searching for deep pressure on duckduckgo. Never heard of the term before, buuuuuut seems interesting...

I used to do this as a child, alone..
And now I ask YOU, have you heard of this deep pressure term before? What are your experiences? (Now u be the entertainer! I'm done with pretending!)

Yup, that's completely normal. Try some arm compressors, they're usually sold under a "sensory" labeling.
