Yes, dryness in prayer is normal. Consolations, if and when they happen, are very subtle and fleeting and easy to miss, often because these happen in ways we might not expect. Very rarely are they as obvious as, for example, sudden tears while in the middle of devotions. It's good to follow the commands of the Church, yet probably a way to understand what St. Teresa of Avila was saying is that devotions shouldn't be undertaken as something transactional. Keep at it patiently and diligently every day and look to Our Lady and the Paraclete to guide you.
