Experiences in Meditation: Am I stucked?

I meditate (Shamata) since a few years now. According to my meditation time I have 430 hours meditated. (Just for context related to my question). I stopped smoking weed a few months ago. Practicing now daily. Around 1 hour. My concentration is far better. I realize bodily experiences – mainly feeling "light", sometimes "happy". Body / muscles are sometimes twitching mainly in spine area and nape of the neck. All in all I feel fine and realize that this is a huge motivation in meditating now. It also happens that in ordinary life I can switch (a bit) into this body mode. Fine. But I am a bit anxious, that it will stop here and I do not make further progress – except for maybe feeling better. How do I not get distracted from the ultimate goal? Should I switch now for a time into analytical meditation? But I've once read, that you should switch to this, when you have mastered Shamata for far more than an hour. I have no teacher, no meditation group or whatever. So I am asking here. What are your experiences on your path related to this feeling of "bliss" (light, in my case) I also asked, because I read, that you can be a good meditation practitioner, but it will not help you for your rebirth, if you are distracted / dwelling in this "bliss" moments. Thank you for your time. All the best
