This is just going to basically be an opinion thread since it will be near impossible to figure out unless you dream about shooting heroin and then go out and do it just for the soul purpose of comparing the two sensations. Which doesn't seem practical. Or mabye somone does do that but then you only really have their word to go on.

I personally think yes it can happen. The brain is very powerfull and can extrapalate missing data much like a computer would. So while it may upon testing not be the exact sensation my bet would be it's darn near close to it.
