intense meditation using music: opinion regarding technique

[chombunath]

hi all
greetings i have been an on off user on this forum but lately i have been a serious reader and am also trying work on my meditation techniques.
I had a question for the some of the senior people here. the way i try to achieve the mind body disconnect or as i refer to it the 'happy state' is by focusing or concentrating on certain notes or instruments while listening to music on my headphones, occasionally I even mentally recite a mantra and repeat it over and over again to the tune of the song i am listening to. Though i have never APed or OBEed yet, i think i do get the shivers when i completely intent on the music i am listening to. my question is around 20 minutes to 30 minutes into the deep meditative relaxed state, i start feeling a little uncomfortable around my throat as if it has gone dry and i am usually doing a lot of swallowing movements, more often than not this sensation of lump in my throat ends up being noticed and my concentration veers off.

Another observation i have had is when i am truly focussed and completely relaxed mind state my head usually is turned to the left at a slight degree and is tilted downward and to left. i was wondering if this is anything to do with hemispheric dominance? FYI i am right handed.

any inputs regarding the above query is appreciated.
thanks and peace all
