Do neurons in your brain actually touch each other when receiving messages?

Neurons do not actually touch each other when receiving messages. Instead, they communicate through specialized structures called synapses. When an electrical signal reaches the end of an axon, it causes the release of neurotransmitters, which are chemical messengers. These neurotransmitters diffuse across the synaptic gap, the small space between neurons, and bind to receptors on the dendrites of neighboring neurons. This binding of neurotransmitters to receptors causes changes in the electrical potential of the dendrites, which can either excite or inhibit the neuron. So, while neurons do not physically touch each other, they communicate through the release and binding of neurotransmitters across the synaptic gap.
