No you would freeze to death there. The common day usage
of words like "temperature" and "cloud" is very misleading
in that respect. The density of particles in a "gas cloud"
is smaller than in the best vacuum produced on earth. And a
single particle oscillating wildly due to high temperature
still doesn't carry an impressive total energy budget.

Even our own atmosphere exceeds 1000K above around 300km
and it doesn't fry anything, despite it being much denser
than a gas cloud. Similar with the sun: the surface is about
6000K but the corona has more than a million degrees.
