Guys, Should I drop him a text or consider it as being ghosted?

See now, i can usually take the hint quite well but i'm very confused regarding this situation. To set up the scene, i've been talking to this wonderful person (as friends) for maybe a month or a little over that. We really seem to click! Same hobbies, similar communication styles, similar texting habits and he was a very engaging conversation partner. day before yesterday we bonded a lot and watched a show together as well and ended the night on a high note. Yesterday, he wanted to show me some artwork and we were talking and, again, super fun conversation and then i asked a question (completely harmless, mind you! I asked if he wanted to see my artwork) and he just... disappeared. That was last night and he still hasn't responded and, really, it was a clear question. Not the kind of text that doesn't necessitate a response. To the contrary, really! He's established the pattern of 'if he disappears mid conversation, he'll apologize and let me know what came up' because i made clear i expected that of him (and of course, i hold myself to the same standard).

I'm very confused. Should i check in on him? Am i being ghosted? I'd bet on ghosting but the events leading up to this were so... unalarming. We were joking, having fun and getting to know each other. I was worried something happened but his status is showing as 'playing a game' so i don't believe that's it. My best friend suggested he might be destressing or having a migraine (she gets migraines).

Do i assume i've been ghosted? Do i check in on him? And if i should check in on him, how long should i wait before doing so?
