Hi, could anybody tell me what this is?

After relaxing for a bit I feel strange, and my ears start to ring. This can last for a while. Sometimes The ringing in my ears will intensify to almost unbearable "volume" And it will feel like I am being pulled forwards, And I have a strong desire to follow. Sometimes I will feel a rythmic up and down movement, or else the feelings will reverse and disappear. If anybody could tell me what, If anything this is....

If this is indeed SP, then I will probably try to WILD, if not, DILD.

-Also, which do you recommend for a beginner?
