Summary
This quote suggests that having some kind of existence, even if confined and limited, is preferable to not having any life experience at all. It hints at the uncertainty of death or non-existence, implying that there may be a chance for some form of happiness or fulfillment even in challenging circumstances. However, the speaker is unsure and predicates their expectation of a better life on the premise that having at least a restricted experience is better than nothing.
