I know you can feel pain and shock because i had a dream where scream was chasing after me. I was really scared and i ran out of breath. Then i got stabbed. Nothing to be scared of it terrifying but it doesnt hurt it feels like youve just been bitten by an insect. As for sex, you cant feel it but it turns you on. Walking, no you just feel a bit woozy and taking drugs i have no idea. Other people may feel diffrent things though. Hope this helps!
