I am new to astral but have been lucid dreaming all my life almost every night i bought the book astral in 90 days and was doing real well but then things got a little strange i had this really intense pounding in my chest and i thought i was going to have a heart attack but i was completely calm and when i checked my pulse it was quite slow i tryed to maintain focus but it was so intense i could not, the next time i tryed to astral i was about 40 minuites into it and i got this weird tickling or scratching on my feet and then it felt like i was yanked really hard i instantly jumped up,i realise that these feelings could be part of the transferance but they are so intense and frightening how do i maintain full composure ,i also listen to theta music when i do it becouse it helps me calm my mind any help would be greatly appreciated,thanks julian
