First of all, Thai Yoga Massage is done with your clothes on so I think an important part of receiving Thai massage is to make sure you are wearing comfortable clothes. I have had people come to me wearing jeans and it made it hard for me to get them in different positions and the material was so thick it made it difficult to massage through. Whether you wear pajamas, athletic wear, yoga pants - make sure you can stretch and move. If you are wearing booty shorts, be aware you may be "exposed" in certain stretches. If you get cold easily then you should bring a long sleeve shirt. Hooded sweatshirts are also not ideal as the hood will get in the way.
Secondly, Thai Yoga Massage is similar to having yoga done to you. You can remain very passive and relaxed during the entire session. Try to just lie back and relax while your body is moved and massaged. You will be taken through a wide variety of stretches from seated to lying on your back, to lying on your side, to lying on your stomach. Be prepared for every muscle to be massaged and stretched. If you have any injuries, chronic pain, or health problems discuss them with your practitioner. Thai Massage blends massage, yoga, acupressure and Ayurveda so it can help improve your health in a variety of ways more than just muscular. Unlike table massage, it was designed as a healthcare system so you should take advantage of that and discuss any issues you are having even if it is something that seems minor to you like trouble falling asleep at night.
It is up to you if you want to be quiet or talk. I tell my clients to do what feels natural. If you need the quiet time then you should feel comfortable and supported to not have to talk. If silence is difficult and you want/need to chat then don't feel like you have to bundle it all up inside and feel free to talk. I have some clients that do find it difficult to be quiet but realize the importance of taking time for self care so I give them little exercises to help them focus on and we make it into a small meditation practice for at least one part of the massage.
By the end of the session you should feel like a brand new person! Your circulation will be better, you will feel a little taller, your muscles will feel great and your mind will be relaxed yet energized. Most therapists will give you recommendations on some stretches to do on your own to help you feel wonderful even longer.
