chanting meditations/ mantra meditations

Pranaam,

if there's anyone who practises meditation using a mantra, or by chanting a prayer like the Rudram - is it common to feel a strong rush of energy after a session? Head spins , or you feel a bit giddy and unable to go back to routine immediately? It's only been happening of lAte, it had a very soothing and calming effect on me earlier.

I feel a bit silly asking, since I am told to not give importance to these things, but I can't do anything for 10 mins after I finish a session.

Thank you.

Dear friend ,
Actually when meditation is done with single minded devotion with manthra , the mind becomes very calm with unexplained bliss . May be with chanting of prayers it could experience rush of energy. The reason could be a sort of elated feeling borne out of sense of fulfilment .
