I see you've made some revisions. As this is another draft in which you have moved on to another chapter, the story becomes a little more grounding. You have an audience.
This time the characterization is fuller. You risk bringing the narrator closer to the 'other being' and the audience appreciates the ongoing action. We liked seeing this other being react to the narrator's presence.
The added dialogue and introduction of a third character helps to improve the movement of the plot. No longer interior monologue, the third character helps the narrator to deal with the encounter. He to has experienced this other being.
No more suggestions at this time, except that you continue using the dialogue between the narrator and third character to enhance the interior monologue in the previous chapters.
As the saying goes,
first the Dread,
so remember to Dream the Descent.
No despair- it is the Decision.
