Hi. welcome to OB.
Your orchid looks like it belongs to the oncidium alliance. The pseudobulbs of this type of orchid generally look shriveled like that and the leaves don't look pleated so I don't think it lacks water.
What sort of medium is it potted in? It could be overwatered?
Did you see the flowers. What were they like? The spike looks really tall and airy so it could have Oncidium Sharry Baby which is very popular. Were they small flowers, maroon with pinkish white lip and very fragrant.
I don't know that much about this type of orchid but I'm sure someone who knows more about oncidiums will chime in.
