Hi Steve,
I think you need to use apply() as in the following tiny example:
x <- data.frame(response = c(-121,-131,-135))
apply(x, 1, function(response){rnorm(10, mean = response, sd =
rnorm(10, mean = 9.454398, sd = 1.980136))})

Perhaps:
sim <- apply(x, 1, function(.x)rnorm(1000, .x[2], rnorm(1000,mean=
9.454398,sd=1.980136)))
