Question about blocking out energy

[FunnyDread]

I am 19. I like being a loner and only talk to my mom+3 other siblings (kinda). I want to know what would happen if you block out all human energy so that it doesn't attach to you or you don't attach to it?How would I do this? I feel friends from high school trying to telepathically talk to me, they visit me astrally( I can sometimes see shapes of people in my room also I can hear them sometimes) but I can't personally astral project. I'm learning to ignore it but if there's anyone with advice on how to block all this out I'd really appreciate the help.

I think Closing the Chakras would work better than Void Meditation

If I close them every time im done with my meditations would it slow down my progress? Would I just not be used to the higher conciousness state? I try void meditations but I feel that there is people around me watching and mocking me cause I suck at it and it makes my thoughts run more and more
