Hades and its compartments are spoken in Scripture with locative sense. Attribute it to a spiritual domain if it is easier for you to comprehend, but within the spiritual domain it then will be perceived just as real as any physical domain we might perceive prior to the first death.
Since our Lord and Savior Christ Jesus, is now in a resurrected body, and consumed meat while here on earth prior to the Ascension, it can be safely implied that Hades is just as perceivable to a physical body as was His locative position with us prior to the Ascension and after the Resurrection.
That is not safely implied, it is a speculation that requires one to presume that all, including the damned, will have the omnipotence of Christ following death.
