From how I experienced it, just surrender to it, allow the energy to flow.
Fear is resistance. Resisting the flow is what makes for a rough ride...imagine trying to stop a river from flowing, it would be hard work. Just totally relax and know it will all be ok. Drop your expectations of how you think it should go and think of it as a spiritual joy ride lol. You only have to be aware of it, observe what is happening, thats all that is asked of you, the rest will sort itself out.
The same with the emotional stuff that comes up, just allow it and release. If you need to cry do it but don't analyse the memories or emotions. Its all about letting go and trusting that your higher self knows what's best for you, you need to work with and not against it...you are not at war with yourself so it won't harm you.
If you don't feel like you want to meditate then don't, just do what you feel is right for you as long as fear is not dictating. Remember fear blocks, allowing flows.
I had the heat, the tremors, palpatations and the emotional memories rising. I think they happen at night because thats when you're most relaxed (not resisting). They woke me up but I had no fear of it so it passed quickly.
Hope you find some of this helpful. I can't advise of what to read as I haven't read anything on the subject other than on here and there's plenty to read who have gone through it as others have suggested.
