Eyes forcefully getting open

Hello,

Every time usually after 20-30 minutes, when I start to feel "crushing" sensations and then my body getting lighter and lighter and I feel the sensation of me floating upward, I feel that my eyes are physically forcing to open... if I do nothing they will physically open, and if I go against it, I really need to put pressure on closing them since the force pressure of them trying to open is hard... so when I try to keep them closed against the opening force they start to twitch like hell and usually that's when all the sensations I have experienced just go away, no more floating feeling or vibrations... even if I continue to focus on my object, it still happens
