Imagination is an incredibly powerful tool.
If the body can experience it from an external source, the imagination can be an internal source to do the same.

if it is warmth, use the warmth in the same way.
perhaps heat is to move lower, experiment with it, you may discover something new.
just be careful not to harm yourself, small steps.
search for heat in related kundalini material books, etc..
there may be suggestions and descriptions there that can used.

Hey brother, i have the chills coming up to my crown and sometimes i feel the forehead palpitating softly, the thing is that nothing happens when i notices it during meditation. What gives?
